GI model in .308. 12 flutes, 1-10" twist. I think the GI has looser tolerances as far as chamber dimensions. I'm not worried about beat up brass. Besides a dent and flute marks they look okay as there are no cracks. They get dirty as pigs in a mud hole but so does the rifle Takes a lot of cleaning.
Does anyone load for one? If so, do you recommend small base dies.
My Sierra manual has a section on gas guns but although it is a semi auto the PTR is not a gas gun. I would be thankful for any advice on anything out of the ordinary when loading for this weapon.
