Powder selection is the single most consequential decision a .22 Creedmoor handloader makes. The cartridge’s large case volume and overbore character mean it is uniquely sensitive to burn rate – use the wrong powder family and you will see either dangerously compressed charges or inconsistent combustion. Use the right powder and the .22 Creedmoor delivers the flat trajectory and velocity retention that justify the barrel-life trade-off.
Three powders dominate real-world .22 Creedmoor use: H4350, StaBALL 6.5, and H1000. Each has a legitimate case. This article breaks down where each one wins, where it falls short, and which scenarios favor which choice.
Why the .22 Creedmoor Needs Slow Powder
Before getting into individual powders, it is worth understanding why the burn rate requirement exists.
The .22 Creedmoor case has a large internal volume – derived from the 6.5 Creedmoor – but feeds a .224-bore barrel. The bore is relatively narrow for the amount of gas the case can produce. Fast-burning powders generate peak pressure before the bullet has traveled far enough down the bore to efficiently convert that pressure into velocity. The result is a dangerous pressure spike that does not translate into speed, and accuracy suffers as the pressure curve becomes erratic.
Slow-burning powders generate pressure across a longer portion of the bullet’s travel down the bore, extracting more velocity per unit of powder while keeping the pressure curve predictable. The practical burn rate window for .22 Creedmoor sits in the same range as 6.5 Creedmoor and .30-06 – powders like H4350, StaBALL 6.5, and H1000 are at home here. Powders like Varget or CFE 223, which work well in moderate .224 cases like the .22 ARC, are too fast for the Creedmoor case – they produce excessive pressure before approaching useful velocity.
H4350: The Benchmark
H4350 has been the reference powder for the 6.5 Creedmoor since that cartridge’s introduction, and it carries that reputation directly into the .22 Creedmoor. It is the most widely tested, most documented, and most commonly referenced powder in .22 Creedmoor load data. If you are starting load development and want a well-charted path, H4350 is where most handloaders begin.
Performance characteristics:
H4350 fills the .22 Creedmoor case efficiently with 80gr bullets. Maximum charges run in the 35.5-37.0gr range depending on bullet and seating depth, producing muzzle velocities of 3,150-3,200 fps with 80gr ELD-X from a 26″ barrel. That is the velocity ceiling that makes the .22 Creedmoor relevant as a long-range cartridge – H4350 gets you there.
Accuracy potential with H4350 is high. The powder produces consistent ignition across the Creedmoor’s charge range, and groups in the 0.4-0.6 MOA range are routinely achieved with quality brass preparation and consistent technique.
ES and SD numbers are good – typically 10-18 fps ES and 4-7 fps SD with careful load development. These are not match-grade numbers by the strictest standards, but they are fully adequate for hunting and most long-range shooting applications.
The temperature limitation:
H4350’s weakness is temperature sensitivity. It is an extruded powder, and extruded powders generally exhibit greater velocity variation across temperature extremes than spherical (ball) powder alternatives. Real-world testing documents velocity shifts of approximately 1.5-2.0 fps per degree Fahrenheit with H4350 in the .22 Creedmoor. That translates to a 45-60 fps spread between a cold morning at 20°F and a warm afternoon at 80°F.
For varminting and bench shooting where you develop and shoot at similar temperatures, this is manageable. For hunters who zero in one season and shoot in another – particularly in northern climates where temperature swings between zeroing and hunting can be 50°F or more – the velocity shift pushes point of impact enough at 500+ yards to matter.
Best applications for H4350:
- Maximum velocity loads for varminting and long-range shooting
- Load development baseline – the best-documented starting point
- Use when shooting conditions are temperature-consistent
StaBALL 6.5: The Temperature-Stable Alternative
StaBALL 6.5 is Hodgdon’s temperature-insensitive ball powder designed specifically for the Creedmoor family of cartridges. It entered the .22 Creedmoor loading conversation as the solution to H4350’s primary limitation, and it delivers on that promise.
Performance characteristics:
StaBALL 6.5 runs at a slightly lower velocity ceiling than H4350 in most .22 Creedmoor combinations. Maximum charges with 80gr ELD-X typically produce 3,050-3,150 fps – roughly 50-100 fps below H4350’s peak. For most hunting and long-range shooting applications, that gap is not meaningful. The 2,000 fps threshold for reliable bullet expansion with 80gr ELD-X is still met comfortably at the distances where ethical shots are taken.
What StaBALL 6.5 gives back in velocity, it returns in consistency. Temperature sensitivity tests document velocity variation of less than 1.0 fps per degree Fahrenheit – a significant improvement over H4350. The practical result: a load developed at 60°F performs almost identically at 10°F. For a hunter carrying the same rifle from early October through late January, that predictability is worth more than 75 fps of muzzle velocity.
ES and SD numbers with StaBALL 6.5 are typically outstanding. Single-digit SD – 5-8 fps – is achievable with careful load development, and ES figures of 8-12 fps are common in well-prepared brass. The spherical powder’s uniform particle size produces very consistent ignition, which pays off directly in velocity consistency.
As a ball powder, StaBALL 6.5 also meters cleanly through powder measures. Extruded powders like H4350 can stick, bridge, or produce irregular measures, particularly in cold conditions. StaBALL 6.5 flows freely and consistently, which reduces preparation time and improves charge-to-charge uniformity for high-volume loading sessions.
Best applications for StaBALL 6.5:
- Hunting loads where temperature consistency across seasons matters
- Competition loads where low ES/SD is the primary goal
- High-volume loading where clean metering reduces prep time
- Cold-weather use where extruded powders become problematic
H1000: Maximum Velocity with Heavy Bullets
H1000 is the third pillar of .22 Creedmoor loading, and it occupies a specific niche: maximum velocity with the heaviest projectiles. It burns slower than both H4350 and StaBALL 6.5, and that slower burn rate becomes an asset when driving 88gr ELD-M bullets or comparable heavy .224 projectiles where the pressure requirements are higher.
Performance characteristics:
With 80gr bullets, H1000 does not offer meaningful advantages over H4350 – the burn rate is slower than ideal for that bullet weight and the case volume combination does not produce a significant velocity advantage. The powder shows its value with 88gr and heavier bullets, where maximum charges produce muzzle velocities in the 3,000-3,050 fps range from a 26″ barrel.
That matters because the 88gr ELD-M has a G7 BC of approximately 0.319 – meaningfully higher than the 80gr ELD-X’s G7 BC of around 0.274. Launching that heavier, higher-BC bullet at 3,000+ fps produces a ballistic profile that sustains supersonic velocity past 1,000 yards and drifts less in crosswind than the lighter bullet at any velocity.
Temperature sensitivity with H1000 is moderate – better than H4350 but not as consistent as StaBALL 6.5. For dedicated precision work with heavy bullets at long range, the velocity and BC combination justifies the slight temperature sensitivity trade-off.
Best applications for H1000:
- Maximum performance loads with 88gr ELD-M or heavier bullets
- Dedicated 1,000-yard precision loads where BC advantage matters
- Situations where maximum velocity with heavy bullets outweighs temperature considerations

Practical Recommendations by Scenario
Long-range varminting (75gr V-MAX): H4350 is the clear choice. Maximum velocity with the lighter bullet produces the flattest trajectory and highest impact velocity at extended range. Temperature consistency is less critical when you are shooting at the same range across a single session.
Deer and pronghorn hunting (80gr ELD-X): StaBALL 6.5. The temperature stability ensures your load performs identically whether you are shooting in early season warmth or late-season cold. The 50-100 fps velocity trade-off versus H4350 does not affect ethical hunting range in any meaningful way.
Summer bench and load development (80gr ELD-X): H4350. Maximum velocity and consistent conditions make it the best choice for building your load database and confirming ballistic data.
1,000-yard precision shooting (88gr ELD-M): H1000. The velocity advantage with heavy bullets, combined with the BC advantage of the 88gr projectile, produces the best long-range ballistic profile the .22 Creedmoor can deliver.
Competition shooting with variable weather: StaBALL 6.5. Low ES/SD and temperature insensitivity are the priorities in competition where conditions change between practice and match day.
Winter hunting in cold climates: StaBALL 6.5. Ball powders are inherently more reliable in cold temperatures, and the thermal stability eliminates the need to re-verify point of impact before a cold-weather hunt.
A Note on Factory Ammunition
One documented curiosity worth noting: factory .22 Creedmoor ammunition – primarily from Hornady – has been clocked at approximately 3,180 fps with 80gr bullets in independent testing. Some carefully developed handloads plateau around 3,150 fps despite working up to maximum published charges. This suggests the .22 Creedmoor case is operating near its thermal efficiency ceiling with standard powders and the 80gr bullet.
The practical implication: in the .22 Creedmoor, chasing the last few fps beyond your OCW node often produces diminishing returns – more pressure, faster barrel wear, and marginal velocity gain. Finding a stable, accurate charge that shoots consistent ES/SD is a better outcome than maximum velocity.
Bottom Line
H4350 is where you start, and it remains the best choice when maximum velocity is the priority and temperature variation is not a concern.
StaBALL 6.5 is where you end up for most real-world applications – hunting, competition, and any use case where consistent performance across temperatures matters more than squeezing out the last 75 fps.
H1000 is the specialist’s choice for heavy bullet work at genuine long range, where the BC advantage of the 88gr ELD-M and comparable projectiles justifies the slower powder’s requirements.
All three are legitimate choices. Match the powder to the mission, and the .22 Creedmoor delivers on its considerable promise.
