SO, today I was able to use some stainless steel wool, Hoppes #9, and scrub from chamber to muzzle like a fiend. It was coming out DARK GREY for a good 30 min. After it started to patch cleaner.. "Cleaner".. I slugged the barrel from muzzle to chamber.

I did 2 sluggings, both of them came out smooth, with no sign of rifling. how ever both of them measured in at .25615". so the land to land diameter is 6.506mm. The groove to groove should be 6.5mm-ish... should it not?

Ill have a picture up in a few, but maybe this bore is dirty as F*%K, and just has its grooves FULL of junk? Im going to try fire-lapping.
