Asked this on another site, but want to try here.

On another thread I talked about a problem getting a SS Omega to group after trying numerous powder/sabot/conical combo's - probably 60 shots. Per suggestions, I order some J&B paste to try lapping which hasn't got here yet.

Tried to find it local today -- no luck but picked up some Butch's and a new bore brush.
I've cleaned this bore to where I was getting clean patchs with about every method I know - boiling water, solvents, simple green with jags, brushes, and mop and it shined.

Started with the Butch's with 2 patches on brush followed by 2 to 4 dry. WOW. 30 patch's later, I am still getting crap on every patch - arm is tired and I am taking a break.

Is Butch's that special and/or could their be that much gunk in the rifling? I am going to keep going till I pull clean patches.

Anyone have any ideas or similar experiance? Also seems to be a little tighter the last few inches by the muzzle.
Thanks
Steve
