Description
The Grizzly 357 Mag 180gr WFNGC load, item GC357M12, is a 20 round box of 357 Magnum ammunition from Grizzly Cartridge Company, loaded with a 180 grain hard cast wide flat nose gas check bullet rated at 1400 fps. Grizzly recommends it for hunting deer and bear.

Grizzly 357 Mag 180gr WFNGC Overview
A 180 grain bullet is heavy-for-caliber in the 357 Magnum, and Grizzly drives this hard cast wide flat nose to a rated 1400 fps. Heavy, hard bullets like this turn a 357 revolver or lever gun into a capable tool for deer and black bear at sensible ranges, and for protection in the backcountry. Because the bullet barely expands, it relies on its broad flat nose and weight to cut a full-diameter path and penetrate deeply. Grizzly loads it in nickel-plated cases for smooth extraction and corrosion resistance.
Bullet Design
WFNGC stands for wide flat nose, gas check. The hard cast lead bullet has a broad, flat nose that cuts a full-diameter wound channel, and a copper gas check crimped onto the base protects it from hot propellant gas, reducing leading and allowing higher speed. Hard cast bullets expand very little, so they penetrate deeply, which is why they are popular for deer, bear and other large game.

Intended Use
Grizzly recommends this load for hunting deer and bear. In a lever-action rifle the extra barrel length adds speed and range, while in a revolver it is a strong choice for woods carry and backup on hunts. It is not designed as an urban self-defense round, since hard cast bullets can over-penetrate. Check your state hunting regulations for minimum caliber and energy requirements before using any handgun cartridge on big game.
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.
