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:

• 1935 fps — Marlin 1894 20 inch
• 1897 fps — Marlin 1894 18 inch
• 1871 fps — Marlin 1894 16.5 inch
• 1535 fps — Ruger Redhawk 5.5 inch
• 1466 fps — S&W MT Gun 4 inch
• 1578 fps — Ruger Super Blackhawk 5.5 inch

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 Number) of 12 so, it could be termed a medium/hard cast bullet. It performs as follows:

At an impact velocity of 1,100 fps it will mushroom to about 75 Cal. and should push right through any deer with a broadside shot.

At an impact velocity of 1,500 fps it will mushroom and some of the mushroom will fragment off and send bullet particles flying through the deer, but much of the mushroom and shank will remain intact and should push through any deer hit broadside.

At an impact velocity of 1,900 fps the entire mushroom will turn into shrapnel and send bullet particles all throughout the deer. The shank will remain intact, but will re-mushroom and do damage inside the deer and will probably push through any deer hit broadside.

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.
