High I live in NH. and enjoy shooting black powder rifles and revolvers I currently have a 32 cal traditions rifle I built from a kit and a 36 cal uberti 1851 revolver. I will start with my first question and probably have more as time goes on. I have probably shot my 36 cal 1851 100 or more times with .375 balls and always sheared a little lead as it should but today the same .375 balls came back out on the ram rod so I went with .380 balls. Would temp. have anything to do with that, most of my shooting was done in summer temps but today was 31 deg.
