Shot 60 rounds and all had the little mark on the neck as shown in the picture. Anyone have any insight as to what may be causing this? Should I be concerned? Brass looked great otherwise with this mark being the only possible area of concern.
I do not reload. Gas was tuned for 3 o’clock ejection with lock back on last round. Those are cases from 150gr Federal Non-Typical Whitetail I was using to get on paper and get the gas right.
Aero receivers
20” Rainier Ultra Match Mod 2 in 308
Lantac NIB enhanced bcg
JP SCS with stock spring
10 round pmags
I can provide more build info if needed.
