I loaded my 500 with large magnum pistol primers not knowing they changed the pocket depth to accept large rifle in the newer brass. Lucky for me I caught the high primers after a couple. I would have been in a bind had I loaded these cases. Newer brass has an "R" stamped in it, but dont take my word for it. Good lesson though. Now I check EVERY case for high primers as I seat them.
