Heres one for you guys. I've got a Savage with their built in muzzle-break and its jammed in the "open/break on" position. I can't even budge it with a pair of vice grips on it. Now my question is this, is there a chemical or process out there that would get rid of whatever is in there. I'm guessing its burnt powder. I've tried soaking the break in varsol and parts cleaners. Any help would be greatly appreciated.
