I have been laid up the last two weeks after having foot surgery so I thought this would be a good time to give my guns a good cleaning. I have been using Wads Out plastic solvent and it appears to work pretty well if you can handle the smell. It is not pleasent like Hoppes #9. I was also amazed at how much plastic I got out. I use small pieces of paper towel on a jag with the solvent and just keep working it until it doesn't turn black anymore. Then I run the brass wire brush through it a number of times and then start all over with the solvent and paper towel again. I do this until the bores are like mirrors. I have found that most of the plastic has been build up near the end of the chamber rather than the muzzle.
I like the idea of the power drill and the brass wool. Seems a lot easier on the shoulders.
Two more weeks of no weight on the foot. It's driving me nuts! Grouse season is going to be interesting this year. None of those 10 mile hikes if I can get out at all. If I didn't have a few good Burton Spiller books I would really be in bad shape.
