So, (going back and forth between Utah and Texas) I finally managed to shoot my .243 AR, and the headspacing was good. Next problem,
It's short stroking. Ejects about half the time, never cycles a new round. So I take it back to the gunsmith in this one gunsmith town who helped me assemble it, and my guy (who assured me when we built it that gas isn't an issue,) says my buffer spring is WAY stiff. I guess it is, it's a pain to charge it, I just figured that AR-10 buffer springs are heavier, and I would just have to man up and deal with it. HE SAYS, it's really stiff even for a .308. I assembled the lower years ago, I don't even remember what process I used to order the spring I did. I am running a 1/8 barrel with 100 gr bullets.
Does a .243 need a significantly lighter spring than a .308?
