Jeff, this WILL give you the willies!
I've noticed that after running a pint of water through my barrel, that the “drying” patch comes out black.
This led me to wonder if I could clean my barrel with hot soapy water. After getting home from Saturday's non-hurricane visit to the range, I tried it out.
Hot soapy water does a great job cleaning my CB shot rifle barrel.
I used a lot of paper patches-I'm using paper-towel patches now for almost everything.
This complicates my long-term Ed's red vs Marvel Mystery Oil test that's been running for about a year and a half.
Anyhow, hot soapy water cleans CB barrels just fine.
Jeff-did it give you the willies?
