Description
The Grizzly 357 Mag 158gr Cowboy RNFP load, item GC357M8, is a 50 round box of 357 Magnum ammunition from Grizzly Cartridge Company, loaded with a 158 grain lead round nose flat point (Cowboy) bullet rated at 1000 fps. Grizzly recommends it for target shooting.
Grizzly 357 Mag 158gr Cowboy RNFP Overview
Not every 357 Magnum load needs to be a magnum. This Grizzly Cowboy load uses a classic 158 grain lead round nose flat point at a moderate 1000 fps, built for cowboy action shooting, steel targets and relaxed range sessions. The flat point is safe in tubular magazines, so the same box can feed a single action revolver and a lever-action rifle on the same stage. A 50 round box makes it practical for match days and practice.
Bullet Design
Grizzly’s Cowboy loads use lead bullets at moderate speeds for target shooting and cowboy action matches. A round nose flat point profile feeds reliably and is safe in the tubular magazines of lever-action rifles, and the soft lead bullet is easy on steel targets and bores. Lower speeds keep recoil mild and reduce wear on traditional firearms.
Intended Use
Grizzly lists this as a target shooting load. It is well suited to cowboy action and SASS-style matches, steel plate shooting and plinking. Many cowboy action clubs set velocity and bullet rules, so check your match rules for minimum and maximum speeds and lead-only requirements. It is not intended for hunting or self-defense.
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 Vaquero 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.
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
Loaded to a moderate 1000 fps, this 357 Magnum load is far milder than full-power magnum ammunition. Recoil and muzzle blast are closer to a 38 Special +P, which makes it comfortable for long cowboy action stages and practice sessions in both revolvers and lever-action rifles.
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.
