Stop full length resizing and save your brass, sounds like your chamber is along. Since you are using a gas gun try bumping the shoulder back .002/.003 in-place of full length sizing. Try doing ten rounds and see if they will cycle. I am using a Howa mini bolt action so some of what I am doing might not apply. Good luck.

@triggerbarPhD

what are your thoughts on the 6 arc vs the new 6 max?  I have a grendel so more along these lines but these are interesting case issues.

Not cool to trim everytime
