Frequently Asked Questions
Armscor .357 Magnum Ammo for Sale
Where is Armscor ammo made?
Armscor manufactures ammunition in Marikina City, Philippines, where their main factory produces over 420 million rounds annually. The company also operates a facility in Stevensville, Montana.
Is Armscor ammo safe?
Armscor ammunition meets standard safety specifications and is considered safe to shoot. It performs reliably across thousands of rounds with few reported malfunctions. Opinions on fouling are divided — some shooters find it clean enough, while others consider it notably dirty and avoid it for that reason.
What is the shelf life of .357 Magnum ammo?
Properly stored .357 Magnum ammunition can remain reliable for decades. Most manufacturers cite 10 years, but shooters regularly report success with 25-year-old rounds. For self-defense use, rotating stock every few years is prudent since primer sensitivity can degrade before powder does.
What grain .357 is best for self-defense?
For self-defense, 125-grain hollow points offer higher velocity and proven stopping power, while 158-grain hollow points penetrate deeper. Test both in your revolver and choose whichever shoots most accurately. Hornady Critical Duty 135-grain JHP and Federal Hydra-Shok 158-grain are reliable choices. Expect to pay around $30 per box.
What is the standard velocity of a 357 Magnum?
Standard .357 Magnum velocity ranges from roughly 1,150 to 1,450 feet per second, depending on barrel length and load. Lighter bullets travel faster; heavier ones slower. A 4-inch barrel is the typical reference length. Check individual ammunition specifications for exact figures.
What ammo can a 357 Magnum shoot?
A .357 Magnum revolver safely fires .357 Magnum and .38 Special ammunition. It can also shoot .38 Short Colt and .38 Long Colt. Never fire .357 Magnum ammo in a .38 Special revolver—the pressure is too high. Many shooters use cheaper .38 Special loads for practice.
Is a .357 stronger than a 9mm?
Yes, .357 Magnum generates significantly more velocity and muzzle energy than 9mm. A .357 typically pushes bullets about 30 percent faster, producing greater terminal performance and recoil. The 9mm allows faster follow-up shots and is more manageable for most shooters. The best choice depends on your firearm and intended use.
