Underwood Ammo Handgun Ammunition Features Underwood loads this 10mm round with a 200 grain full metal jacket bullet traveling at 1250 feet per second producing 694 foot pounds of muzzle energy at the muzzle. That combination of weight and velocity makes this a supersonic load well suited to hunting medium game or as a capable defensive round where the shooter wants the added penetration the 10mm cartridge offers over smaller calibers. The full metal jacket bullet profile feeds reliably through a wide variety of 10mm pistols and carbines without the feed sensitivity that some hollow point designs can show in certain platforms. Underwood manufactures each round to tight tolerances which is part of why dedicated 10mm shooters seek the brand out. The nickel plated brass casing resists corrosion in humid or wet conditions and also makes chambered or fired cases easier to spot and identify at the range. This ammunition is rated safe for use with a suppressor giving shooters flexibility for those running a 10mm host with a sound suppressor attached. Packed 50 rounds per box this load gives shooters enough rounds for a solid training session or an extended hunting outing.
