Varminter. Varminter Bullets: This classification of bullets is designed specifically for rapid expansion and instant kills on larger varmints and small game. The shapes of bullets in this classification include hollow point (HP), spitzer pointed flat base (SPT), and semi-pointed (SMP). Bullets in this classification have thin jackets to enhance expansion but with sufficient strength to be fired at the highest muzzle velocities in the cartridges for which they are intended. Bullets labelled as Blitz are designed for medium velocity (under 3600 fps).
