The neck dents are from the case bouncing off the shell deflector behind the ejection port. Put something on there to pad it (velcro works).
SA is full open at 8 turns out from fully closed. Additional clicks "OUT" allows gas to bleed off, so adjust OUT until it won't lock open on an empty mag, and then close it up a click or two for reliability.
Rifle +2 gas is for slower burning powders, so not your problem.
I'm not familiar with Alpha brass, so don't know if it has less capacity than Hornady or is just softer. That brass is UGLY!
What bolt are you running?
