I had nothing but problems with AW mags (tried all 9) with HRD spacer kits and Lapua 6BR brass with 108ELDM. Probably an 80% stoppage rate (At least one stoppage out of each magazine, generally towards the last few when spring tension was easing off). It was amazingly accurate, easy to shoot but feeding from double stack mags didn't work.
This mirrors my experience, which was funny because someone at the range would hand me their AW HRD mag and it would run 100%. I ended up rednecking an anti tilt tail onto the HRD follower and that worked but I moved to 6CM for better feeding. I’ll probably go back to BRA after I run out of CM barrels in the safe next year.
