I would like to get a bushing style sizing die blank from Redding and have it sized with the same chamber reamer that the barrel is done with if this is possible. The sizing die needs to be smaller than the chamber, benchrest techniques do not translate well to service rifle. Just buy an RCBS or Redding die set. Also, I have noticed that alot of parts are available for the M1A from companies like Brookfield Precision. Since the only parts that I have are the receiver and a trigger group I would like to get the best parts to begin with instead of parts that may require a lot of shop work.
Parts is parts.
Don't worry about it. GI stuff works fine. I shoot service rifle only when I get the chance, maybe once a month, but I am starting to consider spare parts problems,etc, and would like your opinion if you have the time. I wish to apologize for the tardiness in my reply. If you like the M-1A, shoot it.
