Do you like to screw a big can to the end of your rifle before you set about riddling targets? Then you surely love the 300 AAC Blackout, one of the most suppressor-friendly rifles in all God’s creation. And you’ll surely love this ammo by Underwood as well – its big, heavy 220 grain bullet dampens its muzzle velocity all the way down to 1,030 fps, which will let a suppressor suppress to its fullest potential.

But its low and slow muzzle velocity isn’t the only feather in this round’s cap. Its bullet is optimized for a flat trajectory even with so little power behind it, as its boat tail enhances its ballistic coefficient and its uniformly dense lead core keeps it balanced in flight. (While this bullet is a hollow point, it’s not optimized for terminal expansion.)

This round’s case features Ducta Bright 7a nickel plating. It lessens friction during cycling to prevent a jam from tripping up feeding or extraction, prevents the kind of corrosion that jeopardizes reliable performance, and resists cracking so you can still reload it back at home. This round’s low flash propellant also complements performance out of a suppressor, making it awesome for night shooting!
