Geez...do you Armor-All your garage floor too? Give it a rest, and run a wet patch through the bore and cylinder chambers to loosen the crud, then a bronze brush. If you're doing more than ten strokes with that brush, you're doing more than the USMC teams at Camp Perry. Then a cpl more wet patches, and one more that's dry, finish with a damp one (if you're going to put it away for a time) with a cheap (can you say CLP) oil and you're done. Let the anal among us detail strip their pieces every time they look at it, and be happy. We're shooters, not cleaners. Rod BTW, sooner or later that electric drill deal is going to seriously mess up your cylinder throats...and good luck finding a chore boy that's not plated steel...I've looked for 3 years without finding one...they're all plated, check out the price of copper, or your jacketed bullets if you doubt.
