or fully feed then lock while using .223 reloads ? This in particular with a AR or HK93 type rifle ?
I fugired the chambers are so loose it shouldn't have any effect.
I'm new to reloading .223 and loaded a dummy round to see where the rifling started in my Colt and vector barrels, I had to run ot .1" beyong max oal before the projectile even engaged the rifling. I know this doesn't relate to case length but I thought it was an indication of built in slop to keep the weapon functional thru combat/ no cleaning time situations ??
I think I'll keep firing and full length re-sizing a couple of cases to grow them til my AR or Vector93 won't lock.

I did buy a LEE case trimmer and it seems to trim to .005 below the max.
