Make sure the primers are installed below case base level. If at or much worse above base level it may cause a misfire. I've been using standard commerical primers for my Garand and M1A for decades without issue. I ream out all my primer pockets with a uniformer in my RCBS case prep machine. After that treatment all properly installed primers are safely below case base level.

I bought a couple thousand primers for a AR - 308. Then I sold the AR. I understand that the brass with these primers are thicker. I've kept these for two reasons, shipping and back up if more Democrats get into office and primers get heavily regulated. I'd trade them on a FTF deal for large rifle primers.
