Figured I share an odd find I have.
I picked up some used 30-30 brass that had some base bulge around head area. I have a Redding 32 win spl die set and took the rod out figuring I’d knock the bulge down before using the 30-30 die. To my surprise it was sizing the necks too!
Approximate ID of the various head stamps (range pick ups or just different rifles) were around .311 and after sizing with the 32 spl, were reading about .306-.307+/-
I don’t have a case gauge nor loaded them up yet, but figured this would be worth a try for anyone else concerned with brass longevity/work hardening
