Gentlemen,
I am attempting to load for a friend of mines .308 internally suppressed bolt gun. Its 18.5" Bbl 1:11.25 twist as far my measurements reveal. I know very little about the suppressed world. He left me with the ammo that was sold with the gun. At this point, I have not broke one down to weigh the bullet. The bullet is a round nose with a deep concave with lead showing. My guess is its in the 200 grain range. Where do start with this combo? I do not have a chronograph.
