My Krag shoots 180, and 220 grain bullets very well, these are the only bullets I have tried, both round nose. I intend to try Hornady ELD match bullets (great B.C.), even if I have to shoot them single fire. These bullets give me nearly half minute results in a 6.5x55 Swedish Mauser. I will also try them in .308. 30-06, and .223. The 6.5x55 ELD'S have a B.C. of 650.
