Thread: 308 case differences?

Ok so you have some hornady brass that has been fired in a chamber thats longer than yours and some RP from a chamber thats been fired in a chamber thats the same or shorter.You will need to adjust your sizing die so that it bumps the shoulder back 1.5-2 thou. If your die is bottomed on the shell holder you can get get a little bit turned off the bottom of the die or the top of the shell holder. sometimes a different die will do the trick or you can get diferent height shell holders. Ill fill in a bit more in the morning.
