Description
The Grizzly 357 Mag 148gr JHP load, item GC357M9, is a 20 round box of 357 Magnum ammunition from Grizzly Cartridge Company, loaded with a 148 grain jacketed hollow point bullet rated at 1700 fps. Grizzly recommends it for hunting deer or smaller game and self defense.

Grizzly 357 Mag 148gr JHP Overview
This 357 Magnum load pairs a 148 grain jacketed hollow point with a high rated velocity of 1700 fps, a figure that reflects Grizzly testing and will vary with barrel length. The result is a fast, flat-shooting magnum load that expands quickly, suiting deer-sized and smaller medium game at handgun and carbine distances as well as personal defense. In a lever-action carbine, the extra barrel length makes the most of its speed and stretches practical hunting range.
Bullet Design
A jacketed hollow point opens up on impact, increasing its frontal area and transferring energy to the target while limiting over-penetration compared with solid bullets. Grizzly loads its JHP rounds for hunting and self-defense, with a jacket designed to hold together as the bullet expands. Expansion depends on impact speed, so the barrel length and velocity of your particular firearm matter.

Intended Use
Grizzly recommends this load for hunting deer or smaller game and for self-defense. The hollow point is designed to expand and deliver energy in the target, which helps limit over-penetration compared with hard cast or Bonebreaker flat point loads. For protection against large bears, Grizzly recommends its heavier non-expanding loads instead. Check your state regulations before using a 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, competition 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.
