My Mod 70 was originally chambered in 270 WSM it might of had a crooked bbl and was straightened out at factory. It was ok for 3 shots then threw the rest. Had it re-barreled to 7mm WSM with a Brux cut rifled bbl.Gun smith didn't free float the for arm. First time shoot accuracy was fair,I floated forearm and it shot better. then learned of a proper sequence in tightening the tang screws. Did that and now I have a shooter.At first I was quite frustrated .
