Sorry I had so little info before. I appreciate everyone's responses. OK basically here's what I did. I shot 4 times with 777. I then used T/C t17 bore solvent to break up the crud ring close to the breach plug (did this a couple times to really make sure I broke the ring up). Next Irotated dry & wet patches a couple times and when Isaw patches coming out clean. I then ran a T/C t17 seasoning patch or two down to season the bore.The barrel looked nice and clean afterwards until I looked down the barrel a couple days later and saw some sort of residue between the rifling. The residue wasn't there after I originally cleaned it. I ran a couple seasoning patches down to get rid of the residue. It looked ok again, but came back a couple days later. Is this normal? Am I doing something wrong? Any help is greatly appreciated.
