We expect that most of the 50 Action Express fans we cater to will use this fine ammunition by Underwood for target shooting. Keeping your aim sharp is always a worthwhile endeavor – especially when you’re harnessing such a powerful handgun. But these rounds will also help keep you safe if you’re confronted by an unruly hog or bear!

This cartridge is loaded with a 300 grain full metal jacket flat nose bullet. It’s nonmagnetic, and it won’t expand after plunging into muscle tissue. But the FMJ FN’s inability to expand is precisely what suits it so well for defense against dangerous beasts. It won’t deliver too shallow a wound channel to access a large, aggressive critter’s vital organs, and its blunt nose profile creates a more injurious wound channel than a round nose FMJ could have inflicted.

This ammo’s propellant is formulated to minimize muzzle flash. You’ll appreciate that feature if you ever have to fire in the dark, as it will keep your eyes better acclimated to your surroundings. You’ll also appreciate the two-fold advantage of nickel-plated brass cases: reduced friction for smoother feeding and ejection in a semi-auto, and enhanced protection against humidity. Suppressor-safe and American-made!
