To reduce the crud ring, buy FFF or (P)-pistol powders. Also buy cooler 209 primers. The easiest to find cool 209 primer is CCI ... not CCI-M (magnum). Many stores keep them behind the gun counter. You must ask for them sometimes.

I swab every 2nd shot using up-to 110 grains 777 FFF with the CCI primers... no crud ring in my Omega. This also gives me a better target reading because quick 2nd shots are sometimes needed while hunting. If you are using 120 grains or more of Pyrodex (or) more than 110 grains of 777, you should carry an extra two patches while hunting. .. one spit patch/one dry patch.
