308 Win – 155 gr Sierra TMK – Black Hills (1C308BHGN10) – 100 Rounds

Long range shooters who run a 308 in steel matches or precision practice want a bullet that holds its velocity and resists wind. This listing is Black Hills Gold 308 Winchester 155 grain Sierra Tipped MatchKing ammo, MPN 1C308BHGN10, sold as a 100 round case. The 155 grain weight has deep roots in Palma competition, and the tipped version brings it up to date.

Black Hills lists this load at 2,750 fps with 2,602 ft-lbs of muzzle energy. The Sierra Tipped MatchKing adds a polymer tip to the proven MatchKing design, which gives a more uniform point from bullet to bullet and a higher ballistic coefficient than an open tip of the same weight. The lighter 155 grain bullet starts faster than a 168 or 175 and stays supersonic a long way in a 308. This is a match bullet built for accuracy on paper and steel, so choose a dedicated hunting bullet when you are going after game.

This ammunition fits rifles chambered in 308 Winchester, including the Ruger Precision Rifle, Remington 700, Tikka T3x, Savage 110 and 10 series, Bergara B-14, Springfield M1A, and AR-10 pattern rifles from Aero, LaRue, and DPMS. A common question is which twist rate suits a 155 grain bullet. Most factory 308 barrels with a 1 in 10 or 1 in 12 inch twist stabilize this weight. Another common question is whether 308 Win can be fired in a 7.62x51mm NATO chamber. In a modern rifle in good condition, commercial 308 is commonly used in 7.62 NATO rifles, but follow your rifle maker’s guidance.

Black Hills 1C308BHGN10 is new production ammunition, not reloads, made in the USA in Rapid City, South Dakota. It uses boxer-primed brass, which makes it a good source of cases for handloaders, and the priming is non-corrosive. This listing ships as 5 boxes of 20 rounds for 100 rounds total from a single lot, so the data you record at the range carries through a full match or training block.
