when I do my 375win a long straight wall case with a big rim on some case the rim is a little mess up and the case won't sit square in the shell plate and catch on the powder funnel and don't start into the sizing die well
auto loader bottle neck should do better but I think that were it starts off wrong
I'll take a look at that next time I tool up for .223. Thats a great thought.
