This week I've been handloading .44 Special cases from a 2 pound coffee can full of tumbled brass that's been sitting on a shelf for about 20 years. I knew there was some ballon head cases in there from finding them in the distant past so I checked every single one of the 450 rds I loaded this week.
Found several mfg of cases that were ballon head, 13 pieces out of that 2 pound coffee can.
