It's quite late at night and I'll compare a short case to a normal one tomorrow and see where the difference is in it but I cant work out how the hell a case can get to short any way
It's not that I've trimmed it to short by mistake. Isn't brass a standard length through production and once its fired in the chamber it basically personalizes it's self with your rifle and then you just neck size every time there after thus way you gain accuracy
The brass will stretch and that's why you check OAL before reloading and trim if necessary
