Owner of Buffalo Bore Tim Sundles on Heavy Deer Grenade 44 Magnum +P Ammunition:
Buffalo Bore's Deer Grenade 44 Mag. +P is a 240gr. Massive, Hollow Nosed, 12 BHN cast bullet with a gas check traveling at the below velocities out of stock, real world, over-the-counter firearms:
This load is designed as the world's premier deer load for 44 mag. The cast bullet is not considered soft, but it is not really a HARD cast bullet either as it only has a BHN (Brinell Hardness Numnber) of 12 so, it could be termed a medium/hard cast bullet. It performs as follows:
Of course all these results will vary depending on how much bone, if any, you hit, etc. This load was designed specifically to do damage to deer sized game and as such does not penetrate like a hard cast flat nosed bullet. This bullet only penetrates about 30% as deep as a typical flat nosed hard cast bullet, which is perfect penetration for shallow game like deer, and medium sized pigs or black bear. This load is your best bet for immediately anchoring any deer with the 44 mag. cartridge that is not CNS (central nervous system) hit.
This bullet is properly alloyed, lubed and is gas checked; it will NOT lead-foul barrels. This load is designed to be safe in ALL/ANY, all steel firearms that are in normal operating condition. We do not recommend its use in lightweight alloyed revolvers as the bullets may jump the crimp.
