Swift A-Frame Heavy Features The Swift A-Frame Heavy bullet in .375 Cal at 270 grains is built around a cross-member copper jacket bonded to a pure lead front core a construction method designed specifically for the punishing impact velocities and dense tissue encountered on dangerous game. That bonded front core is what allows the bullet to expand reliably on contact while still retaining roughly 95 percent of its original weight a figure that matters enormously when a hunter needs the bullet to keep driving forward after the initial impact. The soft semi-Spitzer lead nose runs the length of the bullet and is specifically shaped to resist deformation from the recoil of repeated chambering in the magazine. That nose profile protects bullet integrity long before the bullet ever leaves the barrel which is the first step toward consistent terminal performance downrange. A tapered jacket surrounds the pure lead core and governs the rate of expansion ensuring the bullet opens up in a controlled predictable manner rather than fragmenting on impact with heavy bone or dense muscle. The wraparound jacket at the base is the final piece of the design locking the core in place and preventing the kind of base separation that can rob a bullet of penetration deep into the vitals. Uncoated and built without compromise this .375 inch 270 grain bullet is intended for hunters who need deep controlled penetration above all else. Sold in boxes of 50 the Swift A-Frame Heavy gives handloaders a trusted option for building dangerous game ammunition.
