I have a colt gold cup that had not been fired for 8 months.I took it out to shoot and
found that the accuracy to be horrible.Groups
were all over the place.Took it home and cleaned the barrel and found large carbon deposits on the lands of the rifling.Used shooters choice,outers nitro,outers foul out
and nothing would remove it.Final measure was
to take 22 brush and scrub.Removed some but not all.Shot it accuracy was worse.Carbon is at the muzzle end by the way.HELP!Bad barrel?
I only use jacketed bullets.
