When loading for my .223 I've had a problem with stuck cases. I'm really getting sick of it. One thing I notice though is that it's always the ultramax or black hills brass which I believe is military. Is the rim weaker on mil brass? I clean the dies all the time and make sure I get even coverage with lube but they still stick.
Will I have better results with winny or Remmy brass?
I use Hornady one shot is that nasty rcbs better?

Anybody out there have any tips??
