Frequently Asked Questions

What revolvers can I use Remington UMC 357 Mag ammo in?

.357 Magnum ammunition is designed for revolvers chambered in .357 Mag or those that accept .357 Magnum rounds. Many shooters also use .357 ammunition in revolvers that can fire .38 Special, though .357 cases are longer and should only be used in firearms marked for .357 Magnum. Always verify your revolver's caliber marking before loading.

Is 357 Mag ammo good for hunting?

The .357 Magnum is a capable hunting round, and the 125-grain JSP bullet design in this load is suited to hunting applications. The soft point bullet expands on impact, making it appropriate for small to medium game when shot placement is precise. Performance depends on distance and target, so understand your effective range and ammunition performance limits before hunting.

Can I use .38 Special in a .357 Magnum revolver?

Most .357 Magnum revolvers can safely fire .38 Special ammunition, which offers lower recoil and softer shooting for practice or training. However, always consult your firearm's manual to confirm compatibility. Conversely, .357 Magnum ammunition should never be fired in a revolver marked only for .38 Special.
