use downrange wads to eliminate most of that problem. or chuck your cleaning rod into your cordless drill, dip the brass brush in some acetone and then quickly run it through the bore. do it outside somewhere until you get the hang of it as it can cause a big, fouling slinging mess. good luck with it
I disagree. Chris has it right; however, the Shooter's Choice stuff has to be the Shooter's Choice Shotgun and Choke Tube Cleaner. It works stupendously well; however, it smells. Your wife or SO will most likely forbid you to use it in the house. I do anyway, and say I have no idea what that smell is when she gets home. Neither one of us is fooled.
After cleaning the bore really well, use Slip2000 EWL with a mop through the bore a few times. After doing this, the plastic will come out in one sheet. you won't ever have to go through what all the rest of these guys are telling you to do. Best way to prevent it is too not let it happen in the first place!
A lot of us, me included, got fooled with acetone bs! It is in Ed's bore cleaner but does nothing! It is worthless for plastic removal! I still am looking! By the way, a lot of these guys make it sound easy but I will wager I could find plastic in a lot of their "clean" barrels! Especially their choke tubes! Tom Rhoads
