What's everyone doing to prep there new Winchester brass? I've measured about a dozen new cases and found most to be 2.02 to 2.05. I've heard some people are running them through a full-length die to re round the case mouth. Anyone doing anything to the flash hole / primer pocket? I plan on using a collet die after they are fire formed. Are you prepping the case mouth on new brass? Inside / outside any help or input would be greatly appreciated, if you are running the brass through a full-length size are you just kissing it with the expander ball or full length sizing. What about case lube? Are you using case lube if just running the ball through mouth?
