i have a .36 cal colrain barrel a under hammer. i have 125 shots thru it and have tried may different loads. i realize there is a bit of a break in period on a barrel. i still am gettin bad flyers, 1 to 2 in, outside of a 1 to 1.25 in grp shot at 25 yds. the patches i find look good. startin to get a little frustrated with it. i am also really watchin my loading sequence to do everything same much the same as possible. any thoughts???
