Owner of Buffalo Bore Tim Sundles on Buffalo Bore 358 Win. Supercharged Ammunition:
Item 41A features a 225gr. Sierra SPTZ-BT @ 2545 fps out of a Ruger Hawkeye. (22 inch barrel) This bullet is suited for all North American big game from small whitetails to Yukon Moose and Bison. You should limit yourself to broadside shots on larger big game like moose and bison. At expected impact velocities, this bullet mushrooms readily, but holds together to penetrate large shoulder or hip bones.
