Swift A-Frame Features The Swift A-Frame bullet in .270 Cal at 130 grains uses a jacketed lead construction built around a soft semi-Spitzer lead nose that runs the full length of the bullet from tip to base. This design protects the bullet from deformation caused by recoil while it rides in the magazine which matters on any hunting rifle carrying a full load of ammunition through rough country. The pure copper jacket is tapered at the tip a feature that controls the rate of expansion so the bullet performs predictably whether the shot is close or the velocity has bled off at distance. That controlled expansion is what separates a bullet built for reliable game-taking performance from one that simply expands as fast as physics allows. Tapering at the base of the core is just as important as the nose design because it is what produces the momentum needed to drive the bullet deep into vital tissue after expansion begins. A wraparound jacket at the base locks the core in place retaining original bullet weight and resisting the kind of deformation that can rob a bullet of penetration. Together these design elements make the .277 inch 130 grain A-Frame suited to medium to large game where both expansion and penetration matter. Sold in boxes of 50 this bullet gives handloaders a dependable repeatable option for serious hunting ammunition.
