Underwood Lead Long Flat Nose Gas Check Handgun Ammunition .44 Rem Mag 305gr FN 1189fps 20/ct
Underwood Lead Long Flat Nose Gas Check .44 Rem Mag handgun ammunition delivers proven stopping power for hunters and sport shooters who demand real-world performance from their big-bore revolver. Each round pairs a 305-grain lead flat nose bullet with nickel-plated brass casing and modern boxer primers, giving you reliable ignition, straightforward reloading, and corrosion resistance in the field or at the range.
The flat nose profile and gas check design work together to maintain velocity and energy through longer shooting strings while feeding reliably through your revolver's cylinder. At 1189 foot-pounds of muzzle energy, this load hits hard enough for hunting applications where controlled penetration and energy transfer matter. The supersonic velocity and lead construction make this a time-tested choice for handgunners who take their .44 Magnum seriously—whether you're reaching out past 50 yards or relying on it for backcountry defense.
Non-corrosive and reloadable, these rounds let you build your own supply without worrying about spent cases pitting your brass or primers. The nickel plating keeps cases in good condition, and the gas check helps the projectile maintain velocity consistently shot to shot. If you run a suppressor on a .44 Magnum, Underwood confirms these rounds are safe for use with suppressors, giving you flexibility in your setup.
