Matts gun has extracted rounds while firing with no issues whatsoever.. The problem he is having is clearing the chamber during dropping the mag and clearing the gun for cleaning/maintenance.
I was there today and we made sure everything was properly assembled. Gun function tested well. I put my Ruger mag in and it cleared the first time but not after subsequent rounds. Same with his mags.
When we racked the beejeesus out of it the rounds cleared out. A LOT of force was required. It got stuck with the nose slightly cocked to the RH side, case head pretty much in line with breech face.
It seems as though it doesn't want to clear hardball factory rounds. I'm sure we could load shorter rds but it should clear factory.
Thanks for any help
