Swift A-Frame Features The Swift A-Frame in .270 Cal at .277 inch diameter and 140 grains is built around a jacket and core design engineered specifically for controlled expansion and deep penetration on game animals. A soft semi-Spitzer lead nose runs the full length from tip to base while the pure copper jacket tapers at the tip so expansion rate stays controlled across a wide range of impact velocities. This means the bullet performs consistently whether taken at close range or extended distance rather than expanding violently up close and failing to open at range. The taper at the base of the core is equally important generating the momentum needed for reliable penetration on heavier game. A wraparound jacket at the bullet s base is the feature that ties this design together locking the core in place so the bullet retains its original weight through impact rather than shedding mass and losing penetrating power. This construction also protects the bullet from deformation while riding in the magazine under recoil ensuring it chambers and performs exactly as designed shot after shot. The 50-count package gives hunters enough bullets to work up a load and still have a full season s supply on hand. Hunters pursuing medium to large game with a .270 rifle will find the Swift A-Frame a dependable choice for terminal performance.
