60 grain 223 Sierra's

[Johnny Peppers]

My Colt Match Target, 1 in 9, was not shooting as well as I thought it should with the 52, 53, and 69 grain Sierra HPBT Match bullets. After first finding a bad crown from the factory and getting it corrected, the best it would do was 1.25 to 1.50 in. groups with the bullets mentioned. Someone put me on the 55 grain Sierra HPBT bullets and the groups shrunk by almost half. The 55 grain has a longer bearing surface, and apparently the rifle liked it.
