You can rotate the ramrod clockwise with a cleaning patch. You can also use a patch puller on the end of your ramrod & either double or triple-fold the 3" wet patch... this will clean flat-style breech faces real well. When the folded patch reaches the breech, rotate it clockwise with very little pressure -- otherwise you will bend & deform the two little wires on the bottom of the patch-puller jag

Shooters who experience poor results with FFF are the same shooters who use magnum powder charges... which a majority of bores/Powerbelts combinations don't prefer. You always read in any of my posts that Powerbelts generally perform better with 120 grains or less of loose Pyrodex - 105 grains or less of 777 and two pellets.

If you insist on shooting Powerbelts with 110-150 grains 777, fill the bottom hollow cup/base with Bore Butter/Wonderlube 1000 for added protection against blowing a hole right thru it & expect plenty of crud buildup.. even with FFF and a cool 209 primer.

Also, crud buildups with only 85 grains means too hot of a primer -- too hot of a barrel & there's something on the bore wall like a specific solvent or oil that attracting the spent powder. Do not use anything but spit, water, windex, windshield solution or alcohol for best results swabbing the bore & make sure you use an isoprphyl (rubbing) alcohol swab to remove all traces of oils or lubes when you first arrive at the target bench.
