Re: Reloading for the M1A?
You are 100 percent correct. However the Gunsmiths at Quantico knew how to Accurize the rifle. New brass was used for match loads. All loads were spun, ..002 tiir was the match run out limit. More than .002 was used for practice only. As for myself I Seggerate !, Even these days. I spin my loads and mark the high spot on the brass with a majic marker rim to bullet then when chambered mark goes At top (12:00). A national match barrel would last about 5000 rounds. I had a barrel that turned to [censored] at 600 yards but would still hammer at 300. Forget factory loads for they are All crooked. From machine loading as well as the progressive loading presses. Go with the simple single stage. This is the reason bench shooters do not use either !! Ejected brass come out of M1-A's hot as well as Garands then cool and will not go back into the chamber they come from. New brass will stay straight for that is the way they started.
