Just to follow up on the M2 Ball ammo endeavour. I sorted out about ten cases that had obvious corrosion problems to the junk brass bucket. After putting the remaining deprimed cases in the ulrasonic, more corrosion was revealed. The tarnish really hid a lot of the small pinhole type corrosion on the outer cases. So out of 50 rounds I got 21 cases that were suitable to reload.
No complaints though, all the pulled bullets are perfect. The price on these was right as well. A nice lady from my wife's work found these in her late fathers garage and asked me to come get them, as she was scared to handle them.
He also had some old swollen paper shotgun shells that I took, and I am almost scared of them. Just going to salvage the shot on those.
