been lots of good posts recently about removing the carbon ring. armed with all this new info, i went searching for one to try some of the techniques mentioned. since i shoot some midpower loads that sometimes smoke case necks, i was sure i wouldn't have to look very far. these are not hunting rifles that only shoot 3 boxes of ammo a year. i have also, only recently gotten into annealing, so i was about sure my brass would be prone to leaving the deposits. even scoping an 80's vintage .243 bbl that is pristine outside, but about e.o.l. in the throat, i cannot definitively say i've found one. what am i missing? are my cleaning regimens (unitentionally) over zealous? does anyone have any scope pictures they can post?
