Can't seem to get it done right though.
Deprimed, cut down to recommended size, sized in 45 die,and used a 41 Mag die to size the neck down.
But everytime I end up with a smashed 308 case.
Tried different head stamped brass, grease, oil,and about everything else, but still get mashed brass.
No, I'm not trying to size the whole thing, just a smidge on the case mouth.
I know it can be done because I've done it before some years ago, but am getting mighty frustrated.
