Grizzly 10mm 220gr Bonebreaker FP – Rugged Bear Defense Ammo

Description

The Grizzly 10mm 220gr Bonebreaker FP load, item GC10M10, is a 20 round box of 10mm Auto ammunition from Grizzly Cartridge Company, loaded with a 220 grain Bonebreaker flat point bullet rated at 1200 fps with 703 ft-lbs of muzzle energy. Grizzly recommends it for protection against aggressive bears and other dangerous animals.

Grizzly 10mm 220gr Bonebreaker FP Overview

Grizzly calls this its heavy bear load for the 10mm, and the numbers explain why. A 220 grain hard flat point is near the top of the bullet weight range for the cartridge, and Grizzly rates it at 1200 fps with 703 foot-pounds of energy. That makes it one of the more powerful 10mm loads available for outdoorsmen who carry a semi-auto pistol in bear and moose country. The heavy, non-expanding bullet is chosen for deep, straight penetration rather than expansion.

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 designed this load for protection against aggressive bears and other dangerous animals. It is not a target load and not intended as a typical self-defense hollow point for urban use, where over-penetration is a concern. Many owners carry it in a chest or belt holster while hiking, fishing or hunting, and it also suits close-range work on hogs and other tough game where penetration matters.

Firearm Compatibility

This ammunition is made for handguns chambered in 10mm Auto, such as the Glock 20, 29 and 40, the SIG P320 XTEN, Springfield XD-M Elite 10mm, Smith and Wesson M&P 2.0 10mm and 1911-pattern pistols in 10mm, plus revolvers and carbines built for the cartridge. Never fire it in a 40 S&W firearm; the 10mm case is longer and runs at higher pressure.

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

The 10mm Auto is a powerful semi-auto cartridge, and full-power loads like this produce stout recoil and a sharp report. A full-size, steel or heavier polymer pistol, a firm high grip and regular practice help keep follow-up shots on target.

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.
