I have had over 20 barrels and several "receiver/frames" over the years. I've gotten all but two to shoot MOA or better. I gave the 7mm 08 to a friend and he couldn't get it to group either. The second, a 460 S&W MGM barrel I am working on a load for now but there is not a lot of load data for the 460 especially in a rifle length so the going is slow. I have seen some promise using Lehigh "max penetration" lead free bullets so I think with a little tweak here and there it will be good too.
