Swift A-Frame Heavy Features The Swift A-Frame Heavy bullet in .375 caliber uses a cross member copper jacket bonded to a front core a combination engineered to deliver three traits hunters rely on for big game: controlled expansion high weight retention and deep penetration. Swift states this A-Frame design retains roughly 95 percent of its original weight across a wide velocity range meaning the bullet keeps driving forward rather than fragmenting on impact. A soft semi spitzer lead nose runs from the tip of the bullet to its base shielding it from the deforming effects of recoil while chambered rounds wait in the magazine. At 250 grains and a sourced diameter of .375 inch this bullet is built for heavy rifles used on dangerous or thick skinned game. A tapered jacket surrounds the pure lead core which is what allows the bullet to control its expansion rate rather than over expanding at close impact velocities common with big bore cartridges. A wraparound jacket at the base further reinforces the bullet against deformation helping it retain the weight needed to punch through heavy muscle and bone. Each box contains 50 bullets giving a reloader the components to develop a dependable hunting load for their .375 caliber rifle. Hunters looking for an uncoated proven big bore bullet will find the Swift A-Frame Heavy built to perform when the stakes are highest.
