BlitzKing. For rifles, these bullets are designed for explosive expansion in varmints and small game and with accuracy characteristic of the MatchKing bullets. The nose tips of these bullets are made of a proprietary acetyl resin compound, and the sharp tips improve the ballistic coefficient over the traditional flatbase spitzer bullet design. The 55 grain #1502 has a flatbase. The jackets are thin for enhanced accuracy and explosive expansion, but are capable of withstanding high velocities. These bullets are designed to be fired at muzzle velocities up to 4000 fps. For handguns chambered in 6mm TCU, 6mm PPC, 6mm Benchrest Remington, these BlitzKing bullets are superbly accurate and have devastating expansion on varmints and small game at velocities achievable in these handgun cartridges in single-shot pistols.
