Swift A-Frame Features The Swift A-Frame uses a distinctive jacket and core design built around a soft semi spitzer lead nose that runs from the tip to the base of the bullet. That nose shape is protected from deformation under recoil while seated in the magazine keeping the bullet s profile consistent shot after shot. The jacket itself is made from pure copper and because it tapers at the tip the rate of expansion stays controlled regardless of impact velocity giving predictable performance from close to extended range. This consistency makes the A-Frame a trusted choice for hunters loading for a wide variety of big game at varying distances. At the base of the bullet the jacket tapers again a detail that is critical to penetration because it helps the bullet generate and retain the momentum needed to drive deep into game. A wraparound jacket design at the base is another key feature preserving the bullet s original weight and preventing deformation that could otherwise rob it of penetrating energy. At 180 grains and a .30 Cal / .308 diameter this bullet suits popular .30 caliber big game cartridges where controlled expansion and weight retention matter most. For reloaders who want a dependable deep penetrating bullet for big game hunting loads the Swift A-Frame is available for sale at GrabAGun.
