hours can be tiring. In this regard, my opinion is very simple to state: No such thing as too-little recoil exists. I am a big fan of putting the LAW
(Lightweight Air Working) muzzle brake on varmint guns. When using light varminting bullets, this reduces re- coil of most combinations to essentially zero. And, it reduces down-range noise significantly – vermin are not nearly as alerted. Finally, it adds zero to evident muzzle blast from the shooter’s perspec- tive or from the perspective of others on the shooting line. Design matters and the LAW incorporates the best technology that a rocket scientist could reckon along with the best design features I could come up with and the best basic design and quality that a master machinist could produce. It is the ultimate product of the best ideas from all three of us. Yes, I am prejudiced but that does not change the fact that the LAW reduces recoil better than any other conventional brake and it does so without noticeably increasing noise at the shooting line. Within feasibility constraints, no design could produce superior results. 2) With the lighter versions of
these bullets, this offsets the lower BC. With ideal loads in any given cartridge, these bullets will perform properly to greater distance than will any conven- tional bullet. Usually, increase in effec- tive range is about 10 percent. These tables represent typical re-
sults using top-end 22-250 loads with the specified bullet. The 35-grain frangible will typically disintegrate to at least 600 yards (greater than 1,600 fps retained); the 40-grain cannot be expected to frag- ment reliably beyond about 535 yards (greater than 1,900 fps retained); the 55-grain cannot be expected to fragment reliably beyond about 550 yards (greater than 1,900 fps retained). The 35 shoots flatter than the 40 to 500 yards and flatter than the 55 to 600 yards. If the shooter were to zero the gun for each bullet so that maximum rise above line of sight was 2½ inches (which is reasonable for most varminting) the 35 would shoot closer to line-of-sight to beyond 600 yards. At 600 yards, the 55 has a signifi- cant windage advantage, the 40 requires 14 percent greater windage correction, the 35 requires 25 percent greater wind- age correction. Windage difference be- tween the 35 and 40 is only 10 percent. To each his own but with a decent reticle

(such as the Leupold Varmint Hunter’s reticle) I can hold off 48 inches just about as easily as I can hold off 39 inches. So, unless I need more energy and penetra- tion, I will use the 35s. 3) As with the plastic-tipped ad-
vantage, this improves overall accuracy potential for bullets of any given mass. 4) This would justify an entire
article. In brief, a major limiting factor in accuracy with conventional bullets is asymmetric bullet deformation that occurs as the bullet transfers from the case to the rifling. A lead-alloy core is technically
dead (it has zero restitution after defor- mation – no elastic rebound) so, except for the small amount of plastic resistance in the (conventional) jacket, any defor- mation that occurs during this transition is permanent. The core of frangible bul- lets is significantly tougher to deform than a lead core is and a frangible core has significant plastic strength. These two characteristics combine
to reduce asymmetric bullet deforma- tion during the transition. Therefore, bullet-to-rifling jump, case quality, and load straightness are less critical. For other reasons, this does not
mean that these bullets are necessarily more accurate but it does mean that it is far easier to develop accuracy loads us- ing these bullets. For example, the very first group I shot using frangible bullets was under half an inch on-centers at 100 yards for five shots, and that was from a 22 Hornet. After the least possible load development (I tried a different primer), near quarter-inch groups proved pos- sible.
5) Again, we can launch an effec-
tive varminting bullet with a compara- tively good BC at higher velocity. The lighter bullet always wins for typical
varminting. For example, consider ideal loads in a typical 223-chambered rifle using these bullets and loads: Hor- nady 40-grain V-Max (at 3,850 fps) and Hornady 35-grain NTX (at 4,050 fps). Trajectory data shows that the NTX will retain explosive velocity to about 55 yards greater distance and that it will shoot just about as flat, out to maximum feasible distance (where it will still reliably disintegrate). Yes, it will have somewhat greater wind drift but I have always believed that the need to hold off 10 percent more in a crosswind is not really much of a disadvantage. Others might disagree. CONCLUSION
The short version of this story
is that if you have not tried this new type of varminting bullet you probably should. For now, pricing is identical to any similar conventional bullet, so that is not an issue (cost of core material is far less than one penny per bullet in either design). All that matters is performance
and, from my limited experience, these bullets seem to perform excellently. Indeed, as our editor has noted, we live in a golden age of varminting.
