For those of you that swear by solvents alone your kidding yourselves, test them on a peace of lead..I have because I shoot primarily cast in all my revolvers and vintage rifles, you will change your mind because you'll only get some discoloration...As Hawk said it doesn't hurt that's fact and removes the majority of fouling and carbon..I was an Air Force armorer worked on everything from 20 mike to .223 and we never once used a solvent for barrel issues.
How many cast bullets did the military shoot through those barrels?
