A question for the collective mind. Will using Federal Gold Medal .308 168 grain ammunition cause excessive wear or battering to the pieces parts of my as yet to arrive CMP special grade Garand in .308? Federal basically blew off the question by telling me to ask the manufacturer. CMP said it might be a good idea to use an adjustable gas block screw but they were not sure. I have a quantity of other brass to reload and plan on doing so as well. HOWEVER, there is also a large quantity of GM match that a buddy has and wants to trade. I can only use so much through my bolt gun.
Any guidance will be appreciated.
Oh and what are good powders to use in a 308 Garand?
Thanks much,
