Sierra's 180-gr. match bullets have been shooting from .308 Win. ammo in match grade M14NM's, M1's, and various match grade bolt guns with 1:12 twist barrels into 1/3 MOA at 200 yards, 1/2 MOA at 300, 2/3 MOA at 600 and 3/4 MOA at 1000 yard since the 1960's. They were a favorite of the US Army and USMC Rifle teams back then.

Sierra Bullets' has shot theirs into 1/4 MOA at 200 yards with great repeatability; sometimes even smaller groups close to 1/8 MOA.

I've shot Sierra's first 180-gr. HPMK from 30 caliber magnums with a 1:12 twist barrel into near 1/2 MOA at 1000 yards.

Many matches were won in the 1960's and 1970's with Sierra's 190's from 1:12 twist barrels in 7.62 NATO Garands; even some at the Nationals only a few years ago.
