Working on subsonic loads for the PSA 57 Rock and I discovered the CCI 5.56 Military (whitebox) primers were too hard for the striker. They ran just fine in the CMMG MK57 😀

I’m a hand loader and I reload 5.7×28 subsonic. Tricky little things, but I’ve got it figured out finally. I love my CMMG 57. That radial delayed blowback makes a difference.
