357 Magnum Ammo
The .357 Magnum is one of the most versatile handgun cartridges ever developed—powerful enough to take deer and black bear at moderate range, shootable enough in full-size revolvers for regular practice with full-power loads, and chambered in lever-action carbines that gain meaningful velocity from the longer barrel. Revolvers chambered in .357 Magnum also accept .38 Special, giving you a wide spectrum of load options from mild practice rounds to full-power hunting loads in the same gun.

Ballistics Overview
A standard 125-grain .357 load exits a 4-inch barrel at 1,400–1,450 fps, producing over 550 ft-lbs of energy—substantially exceeding .38 Special +P and approaching the territory of 10mm Auto. A 158-grain load runs 1,250–1,300 fps with similar energy. From a lever-action carbine with a 16-inch barrel, velocity increases by another 150–250 fps, extending effective range for hunting applications. The .357 Magnum is one of the few handgun cartridges with real stopping power at 100+ yards from a carbine platform.
Defensive Use
The 125-grain .357 JHP has one of the strongest street performance records of any handgun load, with decades of law enforcement data behind it. Federal 125gr JHP and Speer Gold Dot 125gr are both proven choices for full-size revolvers. For compact or lightweight .357 revolvers, full-power loads produce fierce recoil and significant blast. Many compact .357 carriers opt for .38 Special +P in small revolvers for more manageable recoil while retaining defensive capability.
Hunting Use
The .357 Magnum is adequate for deer and black bear at close range — inside 75 yards from a revolver, or 125 yards from a lever-action carbine where the extra barrel length adds meaningful velocity. Use heavy-for-caliber, controlled-expansion loads (158–180 grain) for hunting — Buffalo Bore, Hornady, and Federal produce purpose-designed hunting loads. Avoid light defensive loads for hunting; the 125-grain hollow points optimized for stopping power aren’t designed for the penetration needed on game animals.
Lever-Action Carbines
The Henry Big Boy and Marlin 1894 lever-action carbines in .357 Magnum are among the most practical and enjoyable rifles available — sharing ammunition with a .357 revolver, gaining 300–400 fps of additional velocity from their longer barrels, and fitting a hunting and home defense role that few other rifle/pistol combinations can match. The combination of a .357 revolver and .357 lever-action carbine represents one of the most recommended paired systems for homestead, ranch, and backcountry use. See our Henry and Marlin pages for lever-action carbine options.
Practice with .38 Special
One of the .357 Magnum’s underappreciated advantages is the ability to practice with mild .38 Special loads in the same revolver. .38 Special is significantly cheaper and produces a fraction of the recoil, allowing high-volume trigger and accuracy practice without the cost or fatigue of full-power .357 training. This makes owning a .357 Magnum revolver more economical than the caliber’s pricing alone suggests. See our .38 Special page for practice load options and pricing.
Frequently Asked Questions: .357 Magnum
Is .357 Magnum good for self-defense?
Yes — .357 Magnum is one of the most effective defensive handgun cartridges ever developed. The 125-grain JHP load has decades of documented law enforcement stopping power data behind it. For shooters who can manage its recoil, .357 Magnum from a quality revolver is an excellent defensive choice. For those who find the recoil excessive, .38 Special +P in the same revolver is a practical alternative.
Can a .357 Magnum revolver shoot .38 Special?
Yes — this is one of the most practical features of the .357 Magnum platform. Any revolver chambered in .357 Magnum safely fires .38 Special and .38 Special +P ammunition. This allows economical .38 Special practice while carrying .357 Magnum for defense. The reverse is not true — .357 Magnum cannot be fired in a revolver chambered only for .38 Special.
What is the best .357 Magnum revolver?
The Smith & Wesson Model 686 and Ruger GP100 are the two most recommended .357 Magnum revolvers. Both are medium-frame designs that handle full-power .357 loads without accelerated wear. The GP100 is known for its toughness; the 686 for its smooth double-action pull. For carry, the Ruger SP101 and S&W J-Frame in .357 are compact options. See our revolvers page for the full selection.
Does Impact Guns carry .357 Magnum ammunition?
Yes. Impact Guns carries .357 Magnum in defensive hollow point and practice FMJ configurations. Call us at 801-999-1903 (Monday–Saturday, 9am–5pm MST) to check current availability.
