I just tumbled my first .38 SC shells (approx. 500). They are mostly Star line brass, maybe a few other brands as they might have accidently been picked up. I have always purchased new brass, but bow I have about 2k used rounds in zip lock bags and I want to reuse them.
I have cleaned them and during the inspection part... I noticed a few that seem to have a bulge towards the base of the shell. I would assume its in the area where the shell isn't supported by the chamber.
What is allowed for sidewall bulge? It might be a tough question to answer, but I couldn't find the answer.
Thanks!
