Sedalia Dave

As GJ pointed out clean up is easy. I have rubber stoppers that I put in the muzzle end of the barrels. Stand up and fill with hot tap water mixed with a little Ballistal or Murphy's Oil Soap. Let sit shile I clean everything else and then remove the stoppers and push the fouling out easy peasy. As for your knockdowns, Pattern your shotgun. You are blowing holes in the center of the pattern. Up the shot charge, Reduce the powder charge, or use a different wad stack.

Yes. Works great STS, Gun Club, or Cheddite hull CB0178-12 wad 7/8 ounce of shot primer of choice 3cc or 35 grains by weight of 3F APP or Shooters World Black. I use about 20 pounds of wad pressure.
