Frequently Asked Questions

What firearms are compatible with Armscor .22 WMR 40-Grain JHP?

This ammunition is designed for any firearm chambered in .22 WMR (also called .22 Magnum), including popular revolvers, bolt-action rifles, and semi-automatic rifles from manufacturers like Ruger, Smith & Wesson, Kel-Tec, and Savage. Always verify your firearm's chamber markings before use, and never fire .22 WMR in a firearm chambered only for .22 LR, as the two cartridges are not interchangeable.

How does a 40-grain JHP perform compared to FMJ in .22 Magnum?

A jacketed hollow point (JHP) is specifically engineered to expand upon impact, creating a wider wound channel and transferring more energy to the target than a full metal jacket (FMJ) round. For hunting small game or controlling pests, the 40-grain JHP offers superior terminal performance. FMJ rounds are generally preferred for target practice and plinking where expansion is unnecessary and cost is a priority.

Is Armscor ammunition reliable for semi-automatic .22 Magnum rifles?

Yes. Armscor manufactures its ammunition to SAAMI and CIP dimensional and pressure standards, which ensures reliable feeding, extraction, and ignition in properly maintained semi-automatic firearms chambered for .22 WMR. As with any rimfire ammunition, it's good practice to keep your chamber and bolt face clean to maximize reliable feeding and consistent ignition across all 50 rounds in the box.
