The guy i got it off was under the impression it was a 1-8 twist but were not 100% sure at this stage, ill be taking it to the gunsmith in afew months to get the action pollished so ill get him to mesure the twist rate at the same time. So far only 2 3 shot groups through it. 100gr seirra game changer group and 85gr seirra hpbt group. The game changers were loaded with a half min max charge of imr4831 and shot sub moa with 2 rounds in the same hole (first shot pulled) and the hpbts were a load that shoot very well in my brothers 6mm rem with another sub moa group. With some load development I'm sure we can get it to drive tacks
