Swift A-Frame Features The Swift A-Frame bullet uses a soft semi-Spitzer lead nose that runs the full length of the bullet from tip to base a design choice that protects the nose from deforming under recoil while chambered in a magazine. The jacket is made from pure copper and tapers at the tip which gives the bullet a controlled predictable expansion rate regardless of the impact velocity encountered in the field. This matters for hunters taking shots at varying distances where impact speed can differ significantly from one shot to the next. A tapered base further supports penetration helping the bullet retain the momentum needed to reach vital organs on tougher game. One of the A-Frame s signature features is its wraparound jacket at the base which locks the core in place and prevents the bullet from shedding weight as it expands through tissue. This retained weight is critical to maintaining a deep effective wound channel on medium to large game animals. At 250 grains and a .338 diameter this jacketed lead projectile carries the mass needed for deep penetration in a .338 caliber rifle. Packaged 50 to a box Swift A-Frame bullets give reloaders the supply needed for both load development and a full hunting season of dependable terminal performance.
