Primer opinions??? I recently had some Win primer issues. Stunned because I've used them for many years with zero problems. Loading 243Win and primers are flattening like pressure issue. However, it's the same recipes I've been using for years. Full grain + under Hodgdon's max. H4350 & H4831. Cases are all the same, trim length, etc. I never load hot as it's very unnecessary. Looks like I may be switching. What the heck is going on with Win primers??? Anybody??
