Grizzly 357 Mag 210gr Bonebreaker FP – Dependable Bear Defense Ammo

Description

The Grizzly 357 Mag 210gr Bonebreaker FP load, item GC357M20, is a 20 round box of 357 Magnum ammunition from Grizzly Cartridge Company, loaded with a 210 grain Bonebreaker flat point bullet rated at 1275 fps. Grizzly recommends it for hunting black bear and protection against aggressive bears and other dangerous animals.

Grizzly 357 Mag 210gr Bonebreaker FP Overview

At 210 grains, this is one of the heaviest bullets you will find loaded in a factory 357 Magnum cartridge. Grizzly pairs the long, hard Bonebreaker flat point with a rated 1275 fps, trading speed for weight and sectional density. Heavy, non-expanding bullets like this are built to drive deep through muscle and bone, which is why they appeal to 357 owners who carry for protection against bears and other large animals. In a lever-action rifle the extra barrel length adds speed and makes it a serious close-range hunting load.

Bullet Design

Bonebreaker is Grizzly Cartridge’s name for its hard, non-expanding flat point bullet. A wide, flat meplat crushes and cuts tissue instead of simply pushing it aside, and because the bullet does not expand, it keeps driving in a straight line for deep penetration through muscle and bone. That is why loads like this are a common choice for protection against bears and other large animals, where reaching the vitals matters more than expansion.

Intended Use

Grizzly recommends this load for hunting black bear and for protection against aggressive bears and other dangerous animals. It is not intended as an urban self-defense round, where over-penetration is a concern. Because the bullet is long, confirm that it chambers and feeds smoothly in your revolver cylinder or lever-action magazine before you rely on it in the field.

Firearm Compatibility

This ammunition is made for revolvers and lever-action rifles chambered in 357 Magnum, such as the Smith and Wesson Model 19, 66, 586 and 686, the Ruger GP100, SP101, Blackhawk and LCR in 357, and Marlin, Henry, Rossi and Winchester lever guns in 357. Do not fire 357 Magnum in a firearm chambered only for 38 Special. Confirm feeding in lever-action rifles, since bullet length and nose shape matter in tubular magazines.

Grizzly Cartridge Company

Grizzly Cartridge Company is an American ammunition maker known for heavy, hard-hitting loads for hunters, outdoorsmen and handgunners who carry in bear country, along with cowboy action, defense and safari ammunition. Its loads are made in the USA, and many are built to run at the upper end of what each cartridge allows, so always match the load to your firearm.

Recoil and Shootability

Full-power 357 Magnum loads produce noticeable recoil and a loud, bright muzzle blast, especially from short barrels. A steel-frame revolver with a 4 inch or longer barrel, or a lever-action carbine, makes them far more comfortable to shoot.

Practice and Testing

Fire at least a box through your own firearm before you rely on this load for hunting or protection. Confirm reliable feeding and extraction, and check where it prints at the distances you expect to shoot, since heavy or fast loads often hit to a different point than light practice ammunition.

Storage and Care

Store ammunition in a cool, dry place in its original box, away from solvents and lubricants that can contaminate primers. Inspect rounds for dents, loose bullets or corrosion before loading.
