Yup, Got an AYA I converted to a Slug/Buckshot gun and after about 15-20 rounds it is full of plastic. Found the shooters choice works good with one of the 12ga Stainless steel brush I got from brownells. Makes the job of cleaning much more pleasand. Spray the barrels, let em it on the bench horizontally for about 10 minutes, (roll em over at about 5 minutes) give em another quick squirt then brush them out. Usually have to repeat this an additional time or two. When clean hit them with a patch soaked in Kroil and done.
Till I found the stainless steel brushes I cussed having to do this job and even avoided taking the gun to the range so I didn't have to battle with the plastic. Now no problem...
