A synopsis and an update:
These are the patches in the OP, .430 ball, bore butter .010 patches
Next move was to Scotchbrite the bore and polish the lands in the crown
Next few shots with 5:1 Ballistol, .440 ball (rather than the .430) .013 patch (instead of .010) which resulted in bits of burning patch everywhere and -0- accuracy couldn't even put a ball on paper at 50 yards
Next I went full out with the bore polishing. Took a fairly close fitting dowel, cut a slit in it and put a sheet long strip of "crocus cloth" (fine) sandpaper in it. Ran it in the drill on high up and down the bore about a dozen times
Took a conical shaped medium grit stone (like a very big Dremel bit), chucked it in the drill and ran it on the ends of the lands.
Cleaned and lubed the gun well
Took it to the range today - forgot my $&@#^ patch material so used a dry strip and my never opened emergency tube of CVA patch lube I keep in the van
At 50 yards, consistently within the 8 ring, and these are the patches
Only thing left that I don't like is that I think I need to do more work on the end of the lands, looks like they're cutting small holes the patch when it's first shove into the barrel
