20rds – 300 AAC Blackout Black Hills 125gr. Sierra TMK Ammo Details

This 300 AAC Blackout cartridge by Black Hills features Sierra’s tipped MatchKing (TMK) projectile. The bullet’s green acetal resin tip reduces the drag it incurs during flight, contributing a ballistic coefficient that you’ll enjoy tremendously while trying to make some harder shots. The TMK’s ballistic coefficient is even further amplified by its expertly angled boat tail, and the uniformity of its core and concentricity of its jacket do wonders for its rotational stability. Accuracy -- that’s what this bullet offers up in spades, and although its terminal performance is unremarkable we can’t picture a varmint that’d be very pleased to have TMK spiraling toward it.

You don’t just give a TMK to some schmoe if you want it to shine -- you give it to an expert operation like Black Hills. The South Dakotan specialist sat this round’s bullet perfectly flat atop the crest of a precision drawn and tapered brass casing, and saw to it that each of these rounds’ propellant charges are interchangeable with one another. That’ll give you the consistent shots which tight groupings hinge upon!]
