Chris: Just Google for Wads Out and this is what I come up with.
Shotgun
Cleaning shotgun barrels after a day of shooting skeet, trap or sporting clays, can take some time. The toughest part is removing the plastic wad residue and powder from the barrel(s). The first step is to coat the inside of your barrel(s) with a powder solvent. I use a special tool that I made from a power screwdriver. It slowly spins the cleaning rod while you run a wet bore brush down the barrel and back. I wrap a small "Bounty" paper towel patch around the brush, so that it holds more cleaning fluid. I prefer to use a solvent called "Wads Out" made by Seminole Gunworks. Quite often, after 3 or 4 passes, it's just about done. Wipe it dry and inspect the barrel(s) to see if you need to repeat this process. When the barrel(s) are clean, just swab the barrel with kroil and wipe most of it off with a dry patch.
