It wasn't a typo. I was implying that if I'm getting this kind of inconsistency with just 500 pieces of 308 brass there has to be just as much if not more with a few 1000 223 mix head stamp and year cases so no wonder I get hard priming 223 as well.
Ahhh, now I understand.....you are right....223 is even harder to make play nice.
nough that the new style crimp remover just doesn't cut down far enough hence the need for the old style cutter that cuts half way to the bottom of the pocket. On the really deep primer crimp pockets I wonder if the Dillon swagging rod would bottom out in the primer pocket before it was able to swag it enough?
I sure don't have all the answers, but I do know that some hard brass
springs back some after swaging and can cause hell. Some swage it again and have some success, but that's even more time lost.
The old RCBS cutter really didn't cut deeper I don't think, but the angle created a wide chamfer that made it look deep. The primers always seated all the way down, with only the primers round appearing to stick up....but not the actual wall of the primer....if that makes any sense. IOW's you could still measure .004 or more recess from the case head in....to the top of the primer.
I still think most of the hell is caused by hard brass spring-back rather than not enough swage....except that obviously over swaging allowing for spring-back would work....except in the cases that DIDN'T spring-back.....then you'd have another mess.
Cutting such rather than swaging is probably the best way for brass that doesn't play nice. You could anneal (soften) the brass, but annealing the base ruins the brass.
Some really old LC 7.62 (1967) that I processed a few years ago was so hard that the swager button sheared a sliver of brass .... rather than swaging it, and deposited it in the bottom of the pockets. I didn't notice and loaded the brass....I got a surprise in the form of a slamfire. (I forgot to check for high primers that day)
Anyway, I found a few more high primers in that group and broke them down. I found a sliver of brass in the bottom of the pockets that held the primers proud....even uniforming didn't catch them because the uniformer just spun as if the pocket was deep enough.....lesson learned.
