Introduction
Barnes Bullets introduced the VARMIN-A-TOR in 2003 from its Mona, Utah facility, entering the dedicated varmint fragmentation category alongside what would later become the Sierra BlitzKing, Hornady V-MAX, and Nosler Varmageddon. This is an important distinction worth stating clearly up front: despite Barnes’s broader reputation built on lead-free monolithic hunting bullets like the Barnes TTSX and Barnes TSX, the VARMIN-A-TOR is a completely separate product line using conventional lead-core, copper-jacketed construction. It is not lead-free, and hunters should not assume otherwise simply because Barnes is the manufacturer most closely associated with lead-free hunting bullets elsewhere in this catalog.
Like the BlitzKing, the VARMIN-A-TOR shares none of the design goals of a hunting bullet. It is engineered specifically for low weight retention and complete, rapid fragmentation on impact – the opposite design priority from the deep-penetrating, weight-retaining monolithic and bonded hunting bullets covered extensively elsewhere on this site. The VARMIN-A-TOR’s job is to disintegrate explosively in the first few inches of contact with a small varmint, producing the dramatic visible effect that prairie dog and ground squirrel hunters specifically seek, not to penetrate deeply or retain mass the way a deer or elk hunting bullet must.
The caliber range covers .204-inch through .257-inch, somewhat narrower than the BlitzKing’s .204-.243-inch range at the bottom but extending slightly further at the top into .257-inch territory the BlitzKing’s documented lineup does not reach. Weight options span 32 to 85 grains, again broadly comparable to the BlitzKing but with the heaviest VARMIN-A-TOR variants (80-85 grains in .257-inch) addressing a niche the BlitzKing’s mainstream lineup, once the questionable 105-grain .264-inch figure is set aside, does not directly cover. For trajectory data on the cartridges most commonly paired with this bullet, see the 204 Ruger ballistics guide, 22-250 Remington ballistics guide, and 223 Remington ballistics guide.
The original article’s comparison section makes a specific claim worth flagging: that the VARMIN-A-TOR “achieves 5% faster breakup than BlitzKing.” This kind of precise percentage comparison between two competing fragmentation bullets should be read as a general directional claim rather than a rigorously measured, independently verified figure – fragmentation speed and consistency depend heavily on impact velocity, target medium, and the specific rifle and load combination, making a clean 5% figure difficult to substantiate as a fixed, universal constant between two product lines.
Disclaimer: Reloading is an inherently dangerous activity. Always consult current published load data from reputable sources (Barnes, Hodgdon, Hornady) before loading any cartridge. Start at the published minimum charge and work up carefully while watching for pressure signs. Never exceed maximum published loads.

Technical Characteristics
Lead-core hollow point, copper jacket: The VARMIN-A-TOR uses a conventional lead core inside a copper jacket, with the hollow-point cavity and jacket geometry engineered specifically to promote rapid, complete fragmentation rather than controlled expansion or weight retention. As with the BlitzKing, low weight retention here is the explicit design goal, not a shortcoming – judging this bullet by hunting-bullet retention standards would be applying the wrong evaluation framework entirely.
Flat-base profile: Unlike the BlitzKing, which includes boat-tail variants in parts of its lineup, the VARMIN-A-TOR’s original article describes a flat-base hollow-point design throughout. Flat-base bullets generally produce somewhat lower BC than an equivalent boat-tail design at the same weight, which is reflected in the VARMIN-A-TOR’s generally lower BC figures compared to the BlitzKing at comparable weights – this is a real, physically grounded difference rather than an inconsistency, and it is the primary reason the VARMIN-A-TOR’s published BCs trail the BlitzKing’s modestly across most of the overlapping weight range.
No polymer tip: This is the most significant technical distinction from the BlitzKing, V-MAX, and Varmageddon, all three of which use a polymer tip to both protect the meplat and assist expansion initiation. The VARMIN-A-TOR instead uses an open hollow-point design without a polymer tip. This has two practical implications: first, the exposed lead tip in the hollow point can be more susceptible to minor deformation from rough handling or magazine feeding compared to a polymer-tip-protected meplat, though this is a minor practical concern rather than a significant functional issue for most hunters. Second, the stated activation threshold of 2,000 fps is somewhat higher than the BlitzKing’s stated 1,600 fps threshold, which is a meaningful practical difference – the VARMIN-A-TOR requires more retained velocity at impact to fragment reliably, which in practice translates to a somewhat shorter effective range for guaranteed dramatic fragmentation compared to the BlitzKing, all else being equal.
Reduced fouling claim: The original article states a 10-15% fouling reduction “compared to all-lead bullets,” which is a notably different and more defensible comparison baseline than similar claims made elsewhere in this series. Most fouling-reduction claims compare a given bullet against “lead-core bullets” generally, which is a confusing comparison when the bullet itself also has a lead core, as is the case here and with the BlitzKing. The VARMIN-A-TOR’s claim specifically compares against “all-lead” bullets – meaning bare lead projectiles without any copper jacket at all, a category rarely used in modern centerfire varmint hunting. This is a more honest framing of the claim, though it also makes the comparison less practically meaningful for most handloaders, since virtually no one is choosing between the VARMIN-A-TOR and a genuinely unjacketed all-lead bullet for varmint hunting in the first place.
High velocity range, modest effective range: Like the BlitzKing, the VARMIN-A-TOR is optimized for high muzzle velocities (3,000-4,000 fps) typical of dedicated varmint cartridges, but its modest BCs and flat-base profile mean effective range for reliable fragmentation and accurate hit probability on small targets tops out around 300 yards for most practical purposes.
Ballistics and Performance
G1 BCs from 0.128 to 0.279 are modest figures, generally trailing the Sierra BlitzKing (0.145-0.270 across its verified mainstream lineup) and the Hornady V-MAX (0.150-0.275) at most comparable weights – a real, physically explicable gap attributable to the VARMIN-A-TOR’s flat-base profile and lack of polymer tip rather than any flaw in the bullet’s intended function.
The 40-grain .224-inch at BC 0.128 and SD 0.114 is the lowest BC in the entire varmint fragmentation comparison set covered on this site, reflecting both the light weight and flat-base profile. This remains entirely appropriate for its intended close-to-mid-range prairie dog and ground squirrel application, where BC matters less than reliable fragmentation at the ranges typical of that hunting style.
The 50-grain .224-inch at BC 0.177 and SD 0.142 is the VARMIN-A-TOR’s most versatile mainstream weight, covering 223 Remington and 22-250 Remington applications for ground squirrels and predators, comparable in role to the BlitzKing 50-grain at BC 0.238, though trailing it in raw BC.
The 70-grain .243-inch at BC 0.279 and SD 0.169 is the VARMIN-A-TOR’s highest-BC mainstream offering, intended for foxes and larger varmints in 243 Winchester – this essentially ties the BlitzKing 70-grain .243-inch at BC 0.299, the closest the two product lines come to direct parity anywhere in their respective lineups.
The 80-grain and 85-grain .257-inch variants at BC 0.265 and 0.272 respectively extend the VARMIN-A-TOR into territory the BlitzKing’s documented lineup does not directly address, intended for 257 Roberts applications on mid-sized varmints and predators where slightly more weight and retained energy at moderate range is useful.
Accuracy of 0.5-0.9 MOA matches the BlitzKing’s stated specification, a reasonable and field-appropriate figure for high-volume varmint shooting at typical ranges.

Comparison Bullets
The original article’s comparison set – Hornady V-MAX, Nosler Varmageddon, and Sierra BlitzKing – is the correct competitive field for the VARMIN-A-TOR, and these four bullets together represent the most commonly compared options in the lead-core varmint fragmentation category.
The Sierra BlitzKing is the VARMIN-A-TOR’s closest direct competitor in design philosophy and price point, both being conventional lead-core fragmentation bullets at similar cost. The BlitzKing’s polymer tip and boat-tail variants give it a modest but consistent BC advantage at most comparable weights, while the VARMIN-A-TOR’s lower 2,000 fps activation threshold compared to… actually requires more velocity, not less, which is worth restating clearly given how easy this distinction is to get backwards: the VARMIN-A-TOR needs higher retained velocity (2,000 fps) to fragment reliably than the BlitzKing does (1,600 fps), making the BlitzKing the more forgiving choice for longer shots where velocity has dropped further from muzzle figures.
The Hornady V-MAX remains the category’s most widely recognized and longest-established competitor, with a broader caliber range extending to .172-inch and BCs (0.150-0.275) that exceed the VARMIN-A-TOR at most comparable weights, owing again to the V-MAX’s polymer tip and generally more aerodynamic profile.
The Nosler Varmageddon offers both tipped and flat-base variants, making it the most directly comparable competitor to the VARMIN-A-TOR’s flat-base-only approach for at least part of its own lineup. BCs (0.140-0.265) are roughly comparable to the VARMIN-A-TOR across the overlapping weight range, with neither bullet holding a clear universal advantage.
The Speer TNT rounds out the most commonly available conventional lead-core fragmenting varmint bullets, offering another budget-friendly option in this category for handloaders comparing the full field. The 243 Winchester vs 22-250 Remington comparison is a useful reference for handloaders deciding between cartridges in this weight class, and the 250 Savage is another older varmint-capable cartridge occasionally paired with .257-inch projectiles like the VARMIN-A-TOR’s heaviest offerings.

Applications and Practical Aspects
Prairie dogs and small varmints (.204-inch, 32 grains): The VARMIN-A-TOR’s lightest weight in 204 Ruger covers the classic high-volume prairie dog shooting application. The cartridge’s exceptionally flat trajectory combined with reliable fragmentation at typical engagement distances makes this combination a longstanding favorite for organized prairie dog hunts. Hodgdon H4895 and Accurate 2230 are documented powder choices for 204 Ruger at this weight.
Ground squirrels and predators (.224-inch, 40-50 grains): This is the VARMIN-A-TOR’s most commonly used weight range, covering 223 Remington and 22-250 Remington applications. Given the VARMIN-A-TOR’s higher 2,000 fps activation threshold, handloaders pushing for maximum effective range should pay particular attention to retained velocity at the target distance compared to what they might expect from the lower-threshold BlitzKing or V-MAX. Hodgdon Varget, Hodgdon H4895, and IMR 4064 are standard choices for 223 Remington; for 22-250 Remington, Hodgdon H380 and IMR 4064 are well documented.
Foxes and larger varmints (.243-inch, 62-70 grains): The 243 Winchester variants extend the VARMIN-A-TOR’s reach to foxes and other larger varmint species. Hodgdon Varget and IMR 4064 remain appropriate choices for 243 Winchester at these weights.
Predators and mid-sized varmints (.257-inch, 80-85 grains): This is the VARMIN-A-TOR’s distinctive offering relative to the BlitzKing, covering 257 Roberts for predator hunting and larger varmint control where slightly more weight and retained energy is useful. 257 Roberts is a somewhat less common modern varmint platform than 223 Remington or 22-250 Remington, making this a relatively specialized application for handloaders already invested in that specific cartridge. The 257 Weatherby Magnum is a related, higher-velocity cartridge in the same bore diameter worth considering for handloaders wanting more reach from .257-inch projectiles, though it is more commonly paired with hunting-weight bullets than dedicated varmint fragmentation designs.
High-volume shooting considerations: As with the BlitzKing, organized varmint hunts often involve firing hundreds of rounds in a single outing. A reliable powder measure or digital powder scale and dispenser speeds up the charge-throwing process considerably, and a quality case trimmer helps maintain consistent case length across large batches prepared ahead of a hunting trip. A dedicated progressive press is worth considering for handloaders who shoot varmints regularly enough to justify the higher output volume over a single-stage setup, and a powder trickler helps dial in precise charge weights when working up a new load.
Not appropriate for deer or big game: As with the BlitzKing, this bears explicit statement – the VARMIN-A-TOR’s thin jacket and low weight retention by design make it entirely unsuitable for deer or larger game, where penetration to the vitals through 8-12 inches of tissue is required. Hunters wanting a different terminal mechanism for big game should look at conventional soft-point, bonded, or monolithic hunting bullets, all covered extensively elsewhere on this site. For smaller-caliber varmint applications below the VARMIN-A-TOR’s .204-inch minimum, such as 22 Hornet, handloaders should look toward dedicated small-caliber varmint bullets from other manufacturers instead.
Reloading
The VARMIN-A-TOR loads similarly to other conventional lead-core varmint bullets, with standard pressure characteristics typical of this construction category.
Primers: Standard small rifle primers for most VARMIN-A-TOR applications. CCI 400, CCI BR-4, and Federal 205 are reliable choices. For 243 Winchester and 257 Roberts applications using large rifle primer brass, CCI 200 and Federal 210 are standard. Federal GM205M match-grade small rifle primer is worth considering for handloaders prioritizing extreme spread consistency.
Cases: Standard brass from Winchester, Remington, Hornady, and Federal are all appropriate. As with the BlitzKing, the high-volume nature of typical varmint hunting outings makes batch consistency in case prep worth prioritizing over the kind of individual-round attention more typical of low-volume big game hunting loads.
Seating depth: Start 0.010 to 0.050 inches off the lands. The VARMIN-A-TOR’s open hollow-point nose, lacking the polymer tip’s meplat protection, is worth handling somewhat more carefully during seating and magazine feeding to avoid minor tip deformation, though this is a modest practical consideration rather than a significant accuracy concern for most handloaders.
Crimp: Light to medium crimp for semi-automatic platforms and high-recoil rifles to ensure reliable feeding and prevent bullet setback. Bolt-action varmint rifles typically do not require crimping.
Velocity verification: Given the VARMIN-A-TOR’s higher 2,000 fps activation threshold compared to several competitors, confirming retained velocity at your typical engagement distance via chronograph is particularly relevant here – calculate retained velocity at your intended maximum range and confirm it comfortably exceeds 2,000 fps rather than just barely clearing the BlitzKing or V-MAX’s lower thresholds. Hodgdon CFE 223 is an additional powder option some handloaders use for 223 Remington loads with this bullet category. A Lyman digital powder scale and Frankford Arsenal case trimmer are useful additions to a high-volume varmint loading bench.

Frequently Asked Questions
Q: Is the Barnes VARMIN-A-TOR lead-free, given that Barnes is known for lead-free hunting bullets?
A: No, and this is worth stating clearly since it is an easy assumption to make incorrectly. The VARMIN-A-TOR is a conventional lead-core, copper-jacketed bullet, completely separate in construction from Barnes’s well-known lead-free monolithic hunting bullets like the TTSX and TSX. Hunters in lead-restricted jurisdictions including California cannot use the VARMIN-A-TOR for hunting applications covered by those restrictions, despite the shared Barnes branding with their lead-free hunting lineup. This is a genuine, easy-to-make mistake worth flagging explicitly, since prior coverage on this site of the closely related Sierra BlitzKing initially misstated the VARMIN-A-TOR’s construction in the same way before being corrected – underscoring how easy this particular assumption is to get wrong without checking the specific product’s actual construction.
Q: How does the VARMIN-A-TOR’s higher activation velocity threshold (2,000 fps vs the BlitzKing’s 1,600 fps) affect practical hunting range?
A: This is a meaningful practical difference. At a given muzzle velocity and BC, the VARMIN-A-TOR will drop below its fragmentation threshold at a shorter range than the BlitzKing would under the same conditions, simply because it needs more retained velocity to begin with. For handloaders pushing toward the outer edge of effective varmint range – 250-300+ yards – this means the VARMIN-A-TOR’s reliable fragmentation zone is somewhat more conservative than the BlitzKing’s, all else being equal. For closer-range varmint hunting where retained velocity comfortably exceeds 2,000 fps regardless of which bullet is used, this distinction matters less in practice.
Q: Why doesn’t the VARMIN-A-TOR use a polymer tip like its main competitors?
A: This appears to be a deliberate design choice from the bullet’s original 2003 introduction, predating the now-standard practice across most of this category of pairing a polymer tip with flat-base or boat-tail varmint bullets. The open hollow-point design without a tip is a simpler, generally less expensive manufacturing approach, which may partly explain the VARMIN-A-TOR’s position at the lower end of the price range within this bullet category, similar in spirit to how the budget Remington Core-Lokt achieves its price point through manufacturing simplicity rather than premium features. The tradeoff is the lower BC and higher activation threshold discussed elsewhere in this article, both of which a polymer tip would generally help address to some degree.
Q: Is the VARMIN-A-TOR a good value compared to the BlitzKing and V-MAX?
A: For handloaders prioritizing cost above all else within the lead-core varmint fragmentation category, the VARMIN-A-TOR is competitively priced. The tradeoffs are a modestly lower BC across most comparable weights and a higher velocity requirement for reliable fragmentation, both of which translate into a somewhat shorter practical effective range than the BlitzKing or V-MAX offer at the same muzzle velocity. For high-volume, close-to-moderate-range varmint shooting where cost per round matters across hundreds of shots in a single outing, this tradeoff is often a reasonable one. For handloaders specifically pursuing longer-range varmint shooting, the BC and activation threshold gap becomes more relevant to consider.
Q: Can the VARMIN-A-TOR be used on coyotes without significant pelt damage?
A: As with the BlitzKing and other fragmentation-style varmint bullets, this depends heavily on shot placement and impact velocity, and pelt damage is a genuine tradeoff inherent to this entire bullet category rather than something specific to the VARMIN-A-TOR. A solid hit through the chest cavity at typical predator hunting ranges will likely produce meaningful pelt damage given the bullet’s fragmentation design. Predator hunters specifically prioritizing pelt preservation generally look toward retained-weight designs rather than fragmenting bullets for that specific priority.
Q: Why does the original article’s caliber range claim (.204 to .257 inches) match the ballistics table exactly, unlike some other bullets covered in this series where the stated range and table don’t align?
A: This is worth noting as a positive consistency check – unlike several other bullet articles in this review series where stated weight or caliber ranges did not match the documented ballistics table (extending beyond it, or including unverified outlier variants), the VARMIN-A-TOR’s original article presents a caliber range and a ballistics table that align cleanly with each other across all seven documented variants. This internal consistency gives more confidence in the data as presented, though as always, current figures should be verified directly with Barnes before finalizing load development, since published specifications can change over time.
Conclusion
The Barnes VARMIN-A-TOR is a budget-oriented, conventional lead-core fragmentation bullet for varmint hunting, distinct from Barnes’s better-known lead-free monolithic hunting lineup despite sharing the same manufacturer. It competes closely with the Sierra BlitzKing and Hornady V-MAX, generally trailing both in BC due to its flat-base, non-tipped design, while requiring a somewhat higher impact velocity (2,000 fps) for reliable fragmentation than its main competitors.
Choose the VARMIN-A-TOR if: you hunt prairie dogs, ground squirrels, or other varmints at close to moderate range in unrestricted areas and want a budget-friendly fragmentation bullet; you specifically need 257 Roberts varmint loads, a niche the BlitzKing’s documented lineup doesn’t directly address; or cost per round is your primary consideration across a high-volume shooting day.
Choose something else if: you regularly shoot at longer varmint ranges where the higher activation threshold and lower BC become limiting factors – the Sierra BlitzKing or Hornady V-MAX offer better performance at extended distance. If you hunt in lead-restricted areas including California, none of the bullets in this fragmentation category are lead-free options – look toward lighter-weight lead-free monolithic hunting bullets like the Barnes TTSX 50-grain or 70-grain .224-inch, or the Lehigh Defense Maximum Expansion 70-grain, instead. If pelt preservation on predators is a priority, the Sierra Tipped GameKing or a similar retained-weight hunting design is more appropriate than any fragmentation bullet. If you need a bullet for deer or larger game, the VARMIN-A-TOR is entirely unsuitable – choose a conventional soft-point, bonded, or monolithic hunting bullet such as the Sierra GameKing or Barnes TTSX instead.
Disclaimer: Reloading involves inherent risks. Always use current load data from Barnes or other published manuals. Start below maximum charges and increase gradually. The VARMIN-A-TOR contains lead and is not legal for hunting in lead-restricted jurisdictions despite Barnes’s broader lead-free reputation – its low weight retention is an intentional design feature for fragmentation, not a defect, and it should never be used for deer or larger game hunting where penetration to the vitals is required. Wear eye protection at all times. The author and myreloading.com are not responsible for injuries or property damage from reloading or shooting handloaded ammunition.
Have you loaded and shot the Barnes VARMIN-A-TOR? Leave a comment with your load details: weight, cartridge, powder, charge, and what you observed in the field. How did it compare to a Sierra BlitzKing or Hornady V-MAX you may have used in the same caliber? Field reports on the 257 Roberts 80-85 grain variants would be especially valuable given how few resources document that specific application.
Editorial note: Originally published 2024, revised June 2026. The update corrected a significant construction error: the VARMIN-A-TOR is a conventional lead-core, copper-jacketed bullet, not a lead-free design, despite sharing a manufacturer with Barnes’s well-known lead-free TTSX and TSX hunting bullets. This correction was also propagated back to the Sierra BlitzKing article elsewhere on this site, which had previously and incorrectly described the VARMIN-A-TOR as a lead-free alternative. Clarified the VARMIN-A-TOR’s higher 2,000 fps activation threshold compared to the BlitzKing’s 1,600 fps and its practical implications for effective range. Explained the flat-base, non-tipped design as the primary driver of the BC gap against tipped competitors. Noted the VARMIN-A-TOR’s distinctive .257-inch 257 Roberts offering not directly addressed by the BlitzKing’s documented lineup. Added FAQ covering six common questions, including explicit correction of the lead-free misconception. Applied full internal linking throughout.
