Grizzly .44 Magnum +P+ 360gr Bonebreaker flat point ammunition is a heavy, deep-penetrating revolver load that Grizzly recommends for bear defense (Grizzly part no. GC44M+P3). A 360-grain Bonebreaker flat point bullet leaves the muzzle at a rated 1325 fps with 1404 ft-lbs of energy, putting a very heavy bullet behind a wide flat nose that is built to drive straight through bone and muscle. Grizzly loads it as a +P+ .44 Magnum and makes it in the USA. This is a load for the big-bore revolvers carried as a sidearm in bear country, where penetration matters more than expansion. Each box holds 20 rounds, enough to confirm point of impact and still fill the cylinder and a speed loader.
