Davy Posted September 28, 2018 Report Share Posted September 28, 2018 Has anyone tried loading the 22BR with CFE223 for bullets in the 50-55 grain range? Link to comment Share on other sites More sharing options...
Laurie Posted September 29, 2018 Report Share Posted September 29, 2018 You may see ignition issues in the BR with this powder David. In 308, I got 48 hangfires and two misfires in 50 Lapua Palma small primer brass rounds loaded with two bullet weights. The BR with its smaller charges may be OK, but this is undoubtedly a harder challenge for primers than most, even the older ball types. 308 in Lapua standard large primer brass was fine with CFE, just the usual ball powder issues of a very narrow operating range - charges too low and you get wide velocity spreads, hit the pressure area it likes and you see a large MV jump allied to tightened ES, go not much higher still and you're into over-pressures. The 'hotter' Murom 'SR 223 Rem' primer was introduced for American AR High-Power XTC shooters under its local Wolf and Tula brandings a few years ago reportedly because some new ball powders didn't ignite well with the existing SR 5,56 Magnum model. I have a suspicion that the 'problematic powder' was CFE. If so, and if it sees potential ignition issues in the 223 with ~25-27gn charges ............

Davy Posted October 1, 2018 Author Report Share Posted October 1, 2018 Many thanks Laurie, I will stop with Varget although I might just load a very small handful with the CFE223 in the name of science Link to comment Share on other sites More sharing options...
