For years shooters have associated accuracy and superior ballistic performance with one name more than any other - Sierra. On the range or in the field Sierra bullets offer that extra margin of performance that shooters can depend on. Sierra Varminter bullets are 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 labeled as Blitzare designed for medium velocity (under 3600 fps).
