The 22 GT is the .22-caliber member of the GT cartridge family developed by George Gardner of GA Precision and Tom Jacobs – the same duo who created the 6mm GT, itself one of the more important precision rifle developments of the past decade. Introduced around 2021, the 22 GT takes the 6 GT’s established case geometry and necks it down to accept .224-inch bullets, bringing the GT family’s characteristic virtues – short, fat case design, small rifle primer pocket, excellent velocity consistency, magazine-compatible feeding – to the .22 caliber precision rifle world.
The result is a cartridge that pushes 88-90 grain high-BC bullets to approximately 3,300-3,350 fps from 26-inch barrels, produces single-digit velocity extreme spreads from properly developed loads, fits standard short-action magazines without modification, and delivers barrel life of 2,500-3,500 rounds – better than the 22 Creedmoor and competitive with 6mm precision cartridges that operate at similar pressure levels.
For the precision rifle shooter who wants .22 caliber performance in a bolt-action, magazine-fed platform with the consistency that serious competition demands, the 22 GT represents the current state of the art.
The GT Family and Design Heritage
Understanding the 22 GT requires understanding what made the 6mm GT successful. George Gardner designed the 6 GT in 2017 to accomplish two specific goals: match the 6mm Dasher’s accuracy in competition while feeding reliably from standard AICS-pattern magazines. The 6mm Dasher, despite its outstanding accuracy record, has always been finicky in magazine-fed applications because its seating depth requirements and case geometry do not accommodate standard magazine lengths optimally. The 6 GT solved this by engineering the case to meet both requirements simultaneously.
The key features Gardner carried from 6 GT to 22 GT:
Short, fat case geometry: Derived from the 6.5 Grendel/6mm BR case family, the short, fat profile produces more uniform combustion than long, thin cases. The powder column burns end-to-end more consistently because its geometry is closer to spherical. This is part of why the GT family achieves single-digit ES from properly developed loads.
Small rifle primer pocket: The 22 GT uses a small primer pocket despite its case capacity. Smaller primer pockets produce more uniform ignition than large primer pockets at equivalent charge weights – the firing pin force per unit area is higher, producing more consistent primer deformation and ignition timing. This is a deliberate precision engineering decision that costs nothing in performance but contributes meaningfully to ES and SD.
Magazine-compatible overall length: Unlike some precision wildcats where the optimal seating depth for a specific bullet exceeds standard magazine length, the 22 GT is designed to feed from standard short-action AICS magazines at recommended seating depths. This makes the cartridge compatible with PRS-format competition where rapid reloading from box magazines is required.
These features distinguish the 22 GT from the 22 Creedmoor, which achieves higher velocity from a larger case but at the cost of shorter barrel life and less inherent efficiency.
Caliber Description
The 22 GT fires a 0.224-inch diameter bullet from a case measuring approximately 1.510 inches in length – the same length as its parent 6 GT. Maximum overall cartridge length of approximately 2.550 inches is compatible with standard short-action magazine wells. The 30-degree shoulder provides efficient combustion and reliable headspacing.
This is not a SAAMI-standardized cartridge as of 2026, which means no official maximum pressure specification. The precision rifle community uses approximately 61,000 PSI as the practical maximum based on extensive load development experience across the GT case family. All load development must begin conservatively and work up while watching for pressure signs.
Bullet weights in practical use run from 70 to 95 grains, with 80-95 grains being the competition and hunting standard. The Hornady 88-grain ELD-M is the benchmark competition bullet; the Berger 90-grain Hybrid Target and Sierra 95-grain Tipped MatchKing provide alternatives for specific barrels and distances.
Common bullet configurations:
- FMJ: Load development and barrel break-in.
- Hunting (Polymer Tip, VLD): Hornady ELD-X 80-grain and Berger VLD Hunting 85-grain for predator and varmint work where expansion is wanted.
- Match-Grade: Hornady ELD-M 88-grain, Berger Hybrid Target 90-grain, Sierra Tipped MatchKing 95-grain, and Hornady A-Tip Match are the competition standards.
Compatible rifles: the 22 GT is chambered almost exclusively in custom bolt-action builds. GA Precision, Pierce Engineering, Impact Precision, and similar precision rifle builders offer the cartridge as a standard offering. Barrels from Bartlein, Krieger, Hawk Hill, and other top-tier makers are available with 22 GT reamers. There are no major production rifles in 22 GT from standard manufacturers – this is a custom precision rifle cartridge.
Advantages:
- Small rifle primer pocket produces exceptional ES/SD consistency
- Magazine-compatible case geometry – feeds from standard AICS magazines at optimal seating depths
- Better barrel life than the 22 Creedmoor (2,500-3,500 rounds vs 1,800-2,500)
- Inherits the GT family’s proven accuracy record from the 6mm GT platform
- Short-action compatibility in a cartridge that genuinely competes at 800-1,000 yards
Disadvantages:
- No factory ammunition – handloading is mandatory, no exceptions
- No major production rifles – requires custom build investment
- Brass supply limited to a few sources (Alpha Munitions primary)
- No SAAMI standardization – load data is community-developed, not manufacturer-published
- More complex load development than factory-supported cartridges
Technical Characteristics
| Characteristic | Value |
|---|---|
| Bullet Diameter (inches) | 0.224 |
| Case Length (inches) | ~1.510 |
| Max Overall Length (inches) | ~2.550 |
| Bullet Weight Range (grains) | 70-95 |
| Muzzle Velocity (fps) | ~3,350 (88 gr, 26-inch barrel) |
| Muzzle Energy (ft-lbs) | ~2,190 (88 gr) |
| SAAMI Standardized | No – precision wildcat |
| Practical Max Pressure (PSI) | ~61,000 (community standard) |
| Case Design | Short, fat; 30-degree shoulder; small primer pocket |
| Parent Case | 6 GT |
The non-SAAMI status has practical implications: there is no official published maximum, and load development cannot rely on manufacturer-certified data. Use data from established precision rifle community sources, start 10% below reported maximums, and work up carefully. The small primer pocket requires appropriate decapping pins – standard large primer pocket decapping pins will damage the pocket.
Twist Rate Overview
The 22 GT’s heavy, long bullets require fast twist rates for consistent stabilization. The 1:7-inch twist is the standard for builds intended to run 80-95 grain bullets reliably in all weather conditions. A 1:6.5-inch twist provides additional stability margin for the longest 90-95 grain projectiles in cold weather.
| Twist Rate | Optimal Bullet Weight (grains) | Recommended Barrel Length (inches) | Notes |
|---|---|---|---|
| 1:7 | 80-95 | 24-28 | Standard; handles full practical range |
| 1:6.5 | 85-95 | 26-30 | Maximum stability; heaviest bullets |
Barrel length significantly affects velocity. The precision rifle standard for 22 GT is 26-28 inches, which extracts full performance from the moderate powder charges. Shorter barrels (22-24 inches) lose 60-120 fps and are less common in competition builds.
Recoil
The 22 GT generates approximately 10.5 ft-lbs of free recoil energy in an 8.5-pound rifle – between the 22 ARC at approximately 7.8 ft-lbs and the 22 Creedmoor at approximately 12.5 ft-lbs. This mild impulse allows accurate shot calling through the scope at competition magnification (5-25x to 8-32x), which is a meaningful practical advantage in PRS formats where the shooter reads their own trace and impacts.
| Caliber | Recoil (ft-lbs) | Rifle Weight (lbs) |
|---|---|---|
| 22 GT | ~10.5 | 8.5 |
| 22 ARC | ~7.8 | 8.5 |
| 22 Creedmoor | ~12.5 | 8.5 |
| 6mm GT | ~12 | 8.5 |
Caliber Comparison
The 22 GT’s competitive landscape is defined by three direct alternatives: the 22 Creedmoor (higher velocity, shorter barrel life), the 22 ARC (AR-15 compatible, lower velocity), and the parent 6mm GT (heavier, higher-BC bullets, more energy).
22 GT vs 22 Creedmoor: The most practically important comparison for bolt-action precision shooters. The 22 Creedmoor fires 80-grain bullets at approximately 3,500 fps – 150 fps faster than the 22 GT with the same bullet weight. At 1,000 yards that velocity advantage produces approximately 15-20 inches less drop and proportionally less wind drift. The trade-off: the 22 Creedmoor achieves this from a much larger case (6.5 Creedmoor necked to .224), which requires 42-45 grains of slow-burning powder versus the 22 GT’s 33-38 grains. The larger powder charge produces more throat erosion; 22 Creedmoor barrel life is 1,800-2,500 rounds versus the 22 GT’s 2,500-3,500. For shooters who specifically want maximum velocity and accept the barrel life cost, the 22 Creedmoor wins on raw performance. For shooters who value consistency, barrel economy, and the GT family’s proven accuracy platform, the 22 GT is the more defensible choice.
22 GT vs 22 ARC: Different platforms, partially overlapping applications. The 22 ARC was designed for AR-15 use, produces approximately 2,750 fps with 80-grain bullets from a 20-inch AR barrel (versus the 22 GT’s 3,350 fps from a 26-inch bolt barrel), and is magazine-fed from a Grendel-bolt AR platform. The 22 GT is a bolt-action cartridge producing substantially more velocity. They are not competing for the same shooter – the 22 ARC is for AR-15 precision users, the 22 GT is for bolt-action precision users. For the comparison from an AR perspective, see our 22 ARC vs 224 Valkyrie vs 22 Nosler comparison.
22 GT vs 6mm GT: The parent-child comparison. The 6mm GT fires heavier, larger-diameter 103-110 grain bullets with substantially higher BC. At 1,000 yards in a 10 mph crosswind, the 6mm GT drifts approximately 28-30 inches versus the 22 GT’s 35 inches. The 6mm GT produces more energy per shot, which matters for wind calls and for steel plate competitions where dwell time on a target is scored. The 22 GT’s advantage is lower recoil, easier shot calling, and potentially better barrel economics. For pure long-range wind performance, the 6mm GT is superior; for shooters who want .22 caliber character in a precision package, the 22 GT delivers.
| Caliber | Bullet (grains) | Muzzle Velocity (fps) | Muzzle Energy (ft-lbs) | Platform |
|---|---|---|---|---|
| 22 GT | 88 | 3,350 | 2,190 | Bolt-action custom |
| 22 Creedmoor | 80 | 3,500 | 2,173 | Bolt-action custom |
| 22 ARC | 80 | 2,750 | 1,343 | AR-15 or bolt |
| 6mm GT | 109 | 2,950 | 2,107 | Bolt-action custom |
Applications and Practical Use
PRS and Precision Rifle Competition
The 22 GT’s primary application. Its combination of magazine-compatible feeding, single-digit ES from tuned loads, and high-BC bullet performance at competition distances (300-1,000 yards) makes it competitive in PRS-format bolt-gun divisions and NRL Hunter matches. The 35-inch wind drift at 1,000 yards in a 10 mph crosswind is competitive with 6mm precision cartridges that operate at similar recoil levels.
The 88-grain Hornady ELD-M is the most widely used competition bullet – the combination of G1 BC of approximately 0.547 and excellent consistency from lot-to-lot makes it the de facto standard. The 90-grain Berger Hybrid Target and Sierra Tipped MatchKing 95-grain provide alternatives for specific barrel preferences.
The small primer pocket’s contribution to consistency is most visible at these distances. An ES of 8 fps across 10 shots versus 20 fps translates to approximately 0.6 vs 1.5 inches of vertical dispersion at 1,000 yards in standard conditions – the difference between a competitive group and a lost stage.
Long-Range Varmint Hunting
Prairie dog and predator shooting at 600-900 yards, where the 22 GT’s flat trajectory and explosive terminal performance combine to produce decisive results on small animals. The Hornady ELD-X 80-grain provides reliable expansion at the lower impact velocities seen at extended range; the Berger VLD Hunting 85-grain is well-suited to coyote-sized predators where more penetration is wanted than an explosive varmint bullet provides.
Ballistics and Performance
Reference data using Hornady 88-grain ELD-M at 3,350 fps from a 26-inch barrel, G1 BC approximately 0.547, zeroed at 200 yards:
Basic Ballistics Table
| Distance (yards) | Velocity (fps) | Energy (ft-lbs) | Drop (inches, 200-yd zero) |
|---|---|---|---|
| 0 | 3,350 | 2,190 | -1.5 |
| 100 | 3,150 | 1,938 | +1.6 |
| 200 | 2,960 | 1,711 | 0.0 |
| 300 | 2,775 | 1,504 | -7.0 |
| 400 | 2,595 | 1,313 | -20.8 |
| 500 | 2,420 | 1,142 | -42.0 |
Standard conditions: 59°F, sea level, 1.5-inch sight height, zeroed at 200 yards, 26-inch barrel.
For complete 22 GT ballistics data, see the dedicated ballistics page.
Long-Range Performance
At 1,000 yards with a 200-yard zero:
- Velocity: approximately 1,900 fps
- Energy: approximately 705 ft-lbs
- Drop: approximately -220 inches
- Wind drift (10 mph crosswind): approximately 35 inches
The 35-inch wind call at 1,000 yards is excellent for a .22-caliber cartridge, reflecting the high-BC 88-grain bullet’s aerodynamic efficiency. For comparison, a 22 ARC with an 80-grain bullet at 2,750 fps produces approximately 52-55 inches of drift at the same distance – the 22 GT’s velocity advantage compounds meaningfully at extended range.
Reloading
Reloading is mandatory for the 22 GT – there is no factory ammunition and none is anticipated given the cartridge’s custom precision rifle niche. The good news is that the GT family’s case geometry produces excellent handloading results, and the community around this cartridge has developed extensive load data since its 2021 introduction.
Small primer pocket handling: The 22 GT’s small primer pocket requires small rifle decapping pins. Attempting to deprime with a standard large rifle pin will damage the primer pocket. Verify your die set’s decapping pin is appropriate before processing brass.
Seating depth sensitivity: Like all precision wildcats, the 22 GT responds to seating depth tuning. Most barrels find their accuracy node with 0.010-0.030 inches of jump from the lands. Measure your specific chamber’s throat length with a comparator before finalizing seating depth.
Primers and Cases
The 22 GT uses Small Rifle primers. For competition precision work, benchrest primers (CCI BR-4, Federal 205M) minimize ignition variation. CCI 450 Small Rifle Magnum is used by some reloaders with the slowest powders for maximum velocity loads.
Alpha Munitions (ADG) brass is the primary and most widely available source for 22 GT cases. ADG produces premium-quality brass with tight tolerances and consistent weight – appropriate for the precision application. Case availability is adequate for active competition shooters; this is not a brass-starved cartridge in the way some wildcats are.
| Component | Type | Common Brands | Suitable For |
|---|---|---|---|
| Primer | Small Rifle Benchrest | CCI BR-4, Federal 205M | Competition; minimum variation |
| Primer | Small Rifle Magnum | CCI 450 | Maximum velocity; slow powders |
| Case | Brass (primary) | Alpha Munitions (ADG) | All applications; standard source |
Bullets
| Bullet Brand/Model | Weight (grains) | Type | Best For |
|---|---|---|---|
| Hornady ELD-M | 88 | Polymer Tip Match | Competition; benchmark bullet |
| Berger Hybrid Target | 90 | OTM Hybrid | Competition; alternative to ELD-M |
| Sierra Tipped MatchKing | 95 | Tipped HPBT | ELR competition; highest weight |
| Berger LR Hybrid Target | 90 | OTM Hybrid | Long-range competition |
| Hornady A-Tip Match | 88 | Aluminum Tip | Maximum BC competition |
| Hornady ELD-X | 80 | Polymer Tip | Hunting; reliable expansion |
| Berger VLD Hunting | 85 | VLD | Predator hunting |
Powders
The 22 GT’s case capacity (~39-40 grains water) and ~61,000 PSI practical ceiling work best with medium-to-slow extruded powders. The powder selection centers around what produces the lowest ES/SD in a specific barrel – temperature stability matters for competition where matches span morning cold and afternoon heat.
| Powder | Bullet Weights (grains) | Charge Range (grains) | Best For | Notes |
|---|---|---|---|---|
| Hodgdon Varget | 75-88 | 33.0-36.5 | Consistency; most-used powder | Temperature stable; benchmark |
| Hodgdon H4350 | 80-95 | 34.5-38.5 | Versatile; all bullet weights | Good all-around; popular choice |
| Vihtavuori N550 | 85-95 | 34.0-38.0 | Temperature stable; clean | Excellent temp insensitivity |
| IMR 4955 Enduron | 80-90 | 34.0-37.5 | Heavy bullets; reduced fouling | Copper fouling reducer |
| Winchester StaBALL 6.5 | 80-95 | 34.0-38.0 | Temperature stable; ball powder | Ball powder; excellent metering |
| Vihtavuori N150 | 70-85 | 32.5-36.0 | Lighter bullets; shorter barrels | Faster burn; lighter bullets |
| Alliant Reloder 16 | 80-90 | 33.5-37.5 | Temperature stable; competition | Excellent temp insensitivity |
| Alliant Reloder 26 | 85-95 | 35.0-39.0 | Maximum velocity; heavy bullets | Slower burn; 85+ gr |
| Accurate 4064 | 80-90 | 33.0-37.0 | Clean burning; consistency | Ball powder; consistent |
| Hodgdon Hybrid 100V | 75-88 | 33.0-37.0 | Reduced loads; lighter bullets | Ball powder; good metering |
All charge weights are approximate starting-to-maximum ranges based on community-compiled data. The 22 GT has no SAAMI specification. Begin at the minimum, work up in 0.3-grain increments, and monitor pressure signs carefully. Verify against current precision rifle community sources before loading. Use small rifle decapping pins only.
Practical Considerations
Barrel Life
The 22 GT’s barrel life of 2,500-3,500 rounds represents a meaningful improvement over the 22 Creedmoor’s 1,800-2,500 rounds, and is competitive with the 6mm GT and 6mm Dasher that occupy the same precision rifle competitive space. For a competition shooter who burns 500 rounds per season, a 22 GT barrel provides 5-7 seasons of competitive accuracy – reasonable economics for a custom build. For a dedicated barrel life discussion in the related 6mm Dasher context, see our 6mm Dasher barrel life guide.
Custom Build Requirements
Unlike many cartridges covered on this site, the 22 GT genuinely requires a custom rifle. Budget accordingly: a complete custom precision rifle build with quality action, Bartlein or Krieger barrel, and appropriate stock runs $2,500-4,500 depending on components. This is the entry cost for serious precision rifle competition in any custom cartridge, not specific to the 22 GT.
Conclusion
The 22 GT occupies a specific and well-defined niche in the precision rifle world: it is the best-engineered current option for bolt-action .22-caliber competition that requires magazine feeding, provides single-digit ES consistency, and delivers competitive wind performance at 800-1,000 yards without demanding the barrel replacement schedule of the faster 22 Creedmoor.
It is not a casual shooter’s cartridge – no factory ammunition, custom build requirement, and premium component costs set a high floor for entry. For the precision rifle competitor who has committed to that level of investment in the discipline, the 22 GT delivers performance that justifies the commitment.
For shooters evaluating .22 precision options more broadly, the 22 ARC provides excellent performance in an AR-15 with commercial support; the 22 Creedmoor provides higher velocity at the cost of barrel life. The 22 GT sits between them in the bolt-action space – offering better barrel life and inherent consistency than the Creedmoor, with more velocity and better long-range performance than the ARC can achieve.
Editorial note: This article was originally published in 2025 and substantially revised in March 2026. The update added the GT family engineering context section explaining the small primer pocket design decision and magazine-compatible case geometry, expanded the caliber comparison section to four direct comparisons with honest performance trade-offs, added verified charge ranges to the powder table and added the Alliant Reloder 16, Accurate 4064, and Vihtavuori N150, corrected the ballistics table to a 200-yard zero, and added the small primer pocket handling warning for handloaders.

The 22 ARC was designed for AR-15 use, produces approximately 2,750 fps with 80-grain bullets from a 20-inch AR barrel (versus the 22 GT’s 3,350 fps from a 26-inch bolt barrel), and is magazine-fed from a Grendel-bolt AR platform. The 22 GT is a bolt-action cartridge producing substantially more velocity. They are not competing for the same shooter – the 22 ARC is for AR-15 precision users, the 22 GT is for bolt-action precision users. For the comparison from an AR perspective, see our 22 ARC vs 224 Valkyrie vs 22 Nosler comparison.
22 GT vs 6mm GT: The parent-child comparison. The 6mm GT fires heavier, larger-diameter 103-110 grain bullets with substantially higher BC. At 1,000 yards in a 10 mph crosswind, the 6mm GT drifts approximately 28-30 inches versus the 22 GT’s 35 inches. The 6mm GT produces more energy per shot, which matters for wind calls and for steel plate competitions where dwell time on a target is scored. The 22 GT’s advantage is lower recoil, easier shot calling, and potentially better barrel economics. For pure long-range wind performance, the 6mm GT is superior; for shooters who want .22 caliber character in a precision package, the 22 GT delivers.
| Caliber | Bullet (grains) | Muzzle Velocity (fps) | Muzzle Energy (ft-lbs) | Platform |
|---|---|---|---|---|
| 22 GT | 88 | 3,350 | 2,190 | Bolt-action custom |
| 22 Creedmoor | 80 | 3,500 | 2,173 | Bolt-action custom |
| 22 ARC | 80 | 2,750 | 1,343 | AR-15 or bolt |
| 6mm GT | 109 | 2,950 | 2,107 | Bolt-action custom |
Applications and Practical Use
PRS and Precision Rifle Competition
The 22 GT’s primary application. Its combination of magazine-compatible feeding, single-digit ES from tuned loads, and high-BC bullet performance at competition distances (300-1,000 yards) makes it competitive in PRS-format bolt-gun divisions and NRL Hunter matches. The 35-inch wind drift at 1,000 yards in a 10 mph crosswind is competitive with 6mm precision cartridges that operate at similar recoil levels.
The 88-grain Hornady ELD-M is the most widely used competition bullet – the combination of G1 BC of approximately 0.547 and excellent consistency from lot-to-lot makes it the de facto standard. The 90-grain Berger Hybrid Target and Sierra Tipped MatchKing 95-grain provide alternatives for specific barrel preferences.
The small primer pocket’s contribution to consistency is most visible at these distances. An ES of 8 fps across 10 shots versus 20 fps translates to approximately 0.6 vs 1.5 inches of vertical dispersion at 1,000 yards in standard conditions – the difference between a competitive group and a lost stage.
Long-Range Varmint Hunting
Prairie dog and predator shooting at 600-900 yards, where the 22 GT’s flat trajectory and explosive terminal performance combine to produce decisive results on small animals. The Hornady ELD-X 80-grain provides reliable expansion at the lower impact velocities seen at extended range; the Berger VLD Hunting 85-grain is well-suited to coyote-sized predators where more penetration is wanted than an explosive varmint bullet provides.
Ballistics and Performance
Reference data using Hornady 88-grain ELD-M at 3,350 fps from a 26-inch barrel, G1 BC approximately 0.547, zeroed at 200 yards:
Basic Ballistics Table
| Distance (yards) | Velocity (fps) | Energy (ft-lbs) | Drop (inches, 200-yd zero) |
|---|---|---|---|
| 0 | 3,350 | 2,190 | -1.5 |
| 100 | 3,150 | 1,938 | +1.6 |
| 200 | 2,960 | 1,711 | 0.0 |
| 300 | 2,775 | 1,504 | -7.0 |
| 400 | 2,595 | 1,313 | -20.8 |
| 500 | 2,420 | 1,142 | -42.0 |
Standard conditions: 59°F, sea level, 1.5-inch sight height, zeroed at 200 yards, 26-inch barrel.
For complete 22 GT ballistics data, see the dedicated ballistics page.
Long-Range Performance
At 1,000 yards with a 200-yard zero:
- Velocity: approximately 1,900 fps
- Energy: approximately 705 ft-lbs
- Drop: approximately -220 inches
- Wind drift (10 mph crosswind): approximately 35 inches
The 35-inch wind call at 1,000 yards is excellent for a .22-caliber cartridge, reflecting the high-BC 88-grain bullet’s aerodynamic efficiency. For comparison, a 22 ARC with an 80-grain bullet at 2,750 fps produces approximately 52-55 inches of drift at the same distance – the 22 GT’s velocity advantage compounds meaningfully at extended range.
Reloading
Reloading is mandatory for the 22 GT – there is no factory ammunition and none is anticipated given the cartridge’s custom precision rifle niche. The good news is that the GT family’s case geometry produces excellent handloading results, and the community around this cartridge has developed extensive load data since its 2021 introduction.
Small primer pocket handling: The 22 GT’s small primer pocket requires small rifle decapping pins. Attempting to deprime with a standard large rifle pin will damage the primer pocket. Verify your die set’s decapping pin is appropriate before processing brass.
Seating depth sensitivity: Like all precision wildcats, the 22 GT responds to seating depth tuning. Most barrels find their accuracy node with 0.010-0.030 inches of jump from the lands. Measure your specific chamber’s throat length with a comparator before finalizing seating depth.
Primers and Cases
The 22 GT uses Small Rifle primers. For competition precision work, benchrest primers (CCI BR-4, Federal 205M) minimize ignition variation. CCI 450 Small Rifle Magnum is used by some reloaders with the slowest powders for maximum velocity loads.
Alpha Munitions (ADG) brass is the primary and most widely available source for 22 GT cases. ADG produces premium-quality brass with tight tolerances and consistent weight – appropriate for the precision application. Case availability is adequate for active competition shooters; this is not a brass-starved cartridge in the way some wildcats are.
| Component | Type | Common Brands | Suitable For |
|---|---|---|---|
| Primer | Small Rifle Benchrest | CCI BR-4, Federal 205M | Competition; minimum variation |
| Primer | Small Rifle Magnum | CCI 450 | Maximum velocity; slow powders |
| Case | Brass (primary) | Alpha Munitions (ADG) | All applications; standard source |
Bullets
| Bullet Brand/Model | Weight (grains) | Type | Best For |
|---|---|---|---|
| Hornady ELD-M | 88 | Polymer Tip Match | Competition; benchmark bullet |
| Berger Hybrid Target | 90 | OTM Hybrid | Competition; alternative to ELD-M |
| Sierra Tipped MatchKing | 95 | Tipped HPBT | ELR competition; highest weight |
| Berger LR Hybrid Target | 90 | OTM Hybrid | Long-range competition |
| Hornady A-Tip Match | 88 | Aluminum Tip | Maximum BC competition |
| Hornady ELD-X | 80 | Polymer Tip | Hunting; reliable expansion |
| Berger VLD Hunting | 85 | VLD | Predator hunting |
Powders
The 22 GT’s case capacity (~39-40 grains water) and ~61,000 PSI practical ceiling work best with medium-to-slow extruded powders. The powder selection centers around what produces the lowest ES/SD in a specific barrel – temperature stability matters for competition where matches span morning cold and afternoon heat.
| Powder | Bullet Weights (grains) | Charge Range (grains) | Best For | Notes |
|---|---|---|---|---|
| Hodgdon Varget | 75-88 | 33.0-36.5 | Consistency; most-used powder | Temperature stable; benchmark |
| Hodgdon H4350 | 80-95 | 34.5-38.5 | Versatile; all bullet weights | Good all-around; popular choice |
| Vihtavuori N550 | 85-95 | 34.0-38.0 | Temperature stable; clean | Excellent temp insensitivity |
| IMR 4955 Enduron | 80-90 | 34.0-37.5 | Heavy bullets; reduced fouling | Copper fouling reducer |
| Winchester StaBALL 6.5 | 80-95 | 34.0-38.0 | Temperature stable; ball powder | Ball powder; excellent metering |
| Vihtavuori N150 | 70-85 | 32.5-36.0 | Lighter bullets; shorter barrels | Faster burn; lighter bullets |
| Alliant Reloder 16 | 80-90 | 33.5-37.5 | Temperature stable; competition | Excellent temp insensitivity |
| Alliant Reloder 26 | 85-95 | 35.0-39.0 | Maximum velocity; heavy bullets | Slower burn; 85+ gr |
| Accurate 4064 | 80-90 | 33.0-37.0 | Clean burning; consistency | Ball powder; consistent |
| Hodgdon Hybrid 100V | 75-88 | 33.0-37.0 | Reduced loads; lighter bullets | Ball powder; good metering |
All charge weights are approximate starting-to-maximum ranges based on community-compiled data. The 22 GT has no SAAMI specification. Begin at the minimum, work up in 0.3-grain increments, and monitor pressure signs carefully. Verify against current precision rifle community sources before loading. Use small rifle decapping pins only.
Practical Considerations
Barrel Life
The 22 GT’s barrel life of 2,500-3,500 rounds represents a meaningful improvement over the 22 Creedmoor’s 1,800-2,500 rounds, and is competitive with the 6mm GT and 6mm Dasher that occupy the same precision rifle competitive space. For a competition shooter who burns 500 rounds per season, a 22 GT barrel provides 5-7 seasons of competitive accuracy – reasonable economics for a custom build. For a dedicated barrel life discussion in the related 6mm Dasher context, see our 6mm Dasher barrel life guide.
Custom Build Requirements
Unlike many cartridges covered on this site, the 22 GT genuinely requires a custom rifle. Budget accordingly: a complete custom precision rifle build with quality action, Bartlein or Krieger barrel, and appropriate stock runs $2,500-4,500 depending on components. This is the entry cost for serious precision rifle competition in any custom cartridge, not specific to the 22 GT.
Conclusion
The 22 GT occupies a specific and well-defined niche in the precision rifle world: it is the best-engineered current option for bolt-action .22-caliber competition that requires magazine feeding, provides single-digit ES consistency, and delivers competitive wind performance at 800-1,000 yards without demanding the barrel replacement schedule of the faster 22 Creedmoor.
It is not a casual shooter’s cartridge – no factory ammunition, custom build requirement, and premium component costs set a high floor for entry. For the precision rifle competitor who has committed to that level of investment in the discipline, the 22 GT delivers performance that justifies the commitment.
For shooters evaluating .22 precision options more broadly, the 22 ARC provides excellent performance in an AR-15 with commercial support; the 22 Creedmoor provides higher velocity at the cost of barrel life. The 22 GT sits between them in the bolt-action space – offering better barrel life and inherent consistency than the Creedmoor, with more velocity and better long-range performance than the ARC can achieve.
