The Buffalo Bore Deer Grenade .44 Magnum +P 240gr load (Buffalo Bore part no. 4F20) pairs a 240-grain medium cast bullet with a gas check at 1,550 fps. Buffalo Bore designed it as a premier deer load for the .44 Magnum, using a hollow-nosed cast bullet with a Brinell hardness of 12. Buffalo Bore describes the bullet as medium to hard cast: it mushrooms to about .75 caliber at 1,100 fps impact velocity, and it penetrates only about 30 percent as deep as a typical flat-nosed hard cast bullet, which suits deer-sized game, medium pigs and black bears. The bullet is alloyed, lubed and gas-checked, and Buffalo Bore says it will not lead-foul barrels.
