Frequently Asked Questions
Magtech 357 Magnum Ammo for Sale
Is Magtech ammo good quality?
Magtech ammunition is reliable and good value for range training and target shooting. Made by CBC in Brazil, it meets NATO and SAAMI standards with consistent quality control. It's widely used by recreational shooters and law enforcement. Prices typically run $20–$82 depending on caliber and quantity.
How much is magtech 357 Magnum ammo?
Magtech .357 Magnum ammo typically costs around $25–$45 per 50-round box, depending on grain weight and load type. Lighter target rounds cost less; heavier self-defense loads run higher. Prices vary by retailer, so comparing current listings will get you the best deal.
Is Magtech ammo American made?
Magtech ammunition is manufactured by CBC Global Ammunition, a Brazilian company. However, CBC recently announced a $300 million facility in Oklahoma that will produce Magtech cartridges including 9mm, 5.56mm, and 7.62mm, bringing some production to the United States.
What is the shelf life of .357 Magnum ammo?
Properly stored .357 Magnum ammo remains reliable for decades—many shooters report successful use beyond 25 years. Storage conditions matter most: keep rounds cool, dry, and away from extreme temperatures. For self-defense use, rotating stock every few years is prudent.
What grain .357 is best for self-defense?
For self-defense, 125–158 grain hollow points work best in .357 Magnum. Lighter 125-grain rounds offer faster velocity; heavier 158-grain loads deliver deeper penetration. The 135-grain middle option is also well-regarded — Hornady Critical Duty in .357 Magnum is specifically a 135-grain JHP. Federal Hydra-Shok is another proven option.
What are common uses for Magtech ammo?
Magtech ammunition is commonly used for target shooting, range training, and plinking. Their jacketed hollow point loads suit self-defense and law enforcement. Reloaders value Magtech brass cases for durability across multiple reloads, while steel-cased options attract high-volume shooters wanting economy.
Is Magtech ammo corrosive?
No, Magtech ammo is not corrosive. It uses non-corrosive Boxer primers and comes in brass or polymer-coated steel cases, making it safe for regular use without the corrosion concerns associated with older military surplus ammunition.
Is Magtech ammo brass or steel cased?
Magtech offers both brass and steel-cased ammunition. Brass-cased rounds suit reloaders and premium use, while steel-cased variants use zinc coating for lower cost, making them practical for high-volume range training. They produce multiple variants across calibers ranging from 9mm to .50 BMG.
