405 Grain .459 Bullet Performance

This 405 grain .459 diam bullet killed a bull oryx in 2006 at 85 yards. Shot at sunset. Hole straight thru the heart. Retained weight 405 grains. Incidentally, I plan to use this same bullet to shoot an oryx in 2020.......muzzle velocity was 1234 fps driven by 63 grains GOEX 2F...............FWB
