The Sierra Varminter .22 Cal 45gr Spitzer Bullet (brand part no. 1310) is a component rifle bullet built for rapid expansion and instant kills on larger varmints and small game. Varminter bullets are designed specifically for rapid expansion and instant kills on larger varmints and small game. Sierra builds them with thin jackets to enhance expansion while keeping enough strength to handle the highest muzzle velocities in the cartridges they are intended for. This 45-grain option uses Sierra’s spitzer pointed flat base (SPT) profile without a Blitz or Hornet rating, giving it a broad working range across common .22-caliber varmint cartridges.
