So, what do you do if they are rocking a little bit? I am newish to reloading (but, have read the Barnes and Lyman manuals cover to cover) and this only happens on the magnums. I have a 7mag and 300 WSM
and I see the same issue on both, but no issue on 243, 30-06 or 223. I know they should sit in and not flush, but these are above flush to rock like they do. I use the RCBS hand priming tool and press it all of the way in. I tried the Remington magnum and the regular CCI primers and same result on both. A friend suggested that I make sure the rod seating the primer had the flat end against the primer and the round end down, which has always been the case, but does not seem to improve, I can appreciate a potential safety issue, not to mention some possible accuracy issues. What else is there to fix? Thanks for any input guys!
