I have 2 split cases about a 1/4 inch up from the head stamp.I know that I had to much head space and fixed the problem but some of the brass is spliting now.I cant find eny cracks in the chamber all I can see is the burn macks from the split.I have proble put 20 or 30 rounds through and no real problems.I no the brass is going to be week in these spots what would u do? whould keep the gun or just quit using the brass.
