Hey guys...I'm in the process of building another 6.5 for MDPRS competition. I have a 700 that I wanna rebarrel to 6.5 Creedmoor...I plan on running the Criterion Remage barrel setup...and a PTG bolt assembly, unless I can find a factory 308 bolt for sale. If I would go with the PTG will I need to ream the action before installation?....or can I run a bolt with same specs as I'm running now?....other than bolt face of course....
