OSA Australia have introduced the new 150gr HP from Sierra, made exclusively for OSA and the Australian market. After the success of the 135gr HP, we decided that we needed a bit of extra weight for more penetration on larger game. Available in packs of 100 and 500 through your local dealer.
The Varminter is designed specifically for rapid expansion 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. –SIERRA
