The VRG-4: SP BT-XF PEREGRINE™ SPITZER BOATTAIL is an accurate, high performance, velocity enhanced, bi-metal bullet - designed for long range accurate plains-game hunting requiring flat trajectories, excellent ballistics and consistency. As a result of the shorter bearing-surface and other design criteria, this bullet allows for less chamber-pressure and recoil with increased velocity.
The Spitzer has a purpose-designed mechanical initiator (patent pending), which controls expansion throughout the velocity range for controlled and consistent performance, as well as excellent weight retention. This bullet allows for shooting game on the shoulder (instant knock-down), instead of behind, due to the fact that the design doesn’t result in bullet-failure when hitting bone. The initiator tip is also guaranteed against magazine damage due to recoil.
