As most of us know pistol powder selection is on the thin side, and all I could find last year was a dusty 8# jug of 7625. It works fine for my 9mm but my LRN 45 is having a little trouble.
CZ 97b
5.5gr 7625 230gr LRN 750fps
I was experiencing some 'bolt over base' stoppages which I may have fixed with a different recoil spring. However, my loads are still acting weird.
Most fire and eject fine. On occasion I get one that feels lighter in recoil and the slide makes this two stage 'ker-chunk' return to battery like it didn't come back as far as the others. Some sort of debris comes out as well, doesn't appear to be unburned powder.
Also I keep getting flame coming out of the breech as if the powder is still burning upon extraction. Fired cases are fairly dirty.
Bottom line, is this powder too slow for heavier 45's, and should/can I up the charge a bit to help?
