Went thru and was cleaning my 2 benelli semi autos today and as i was admiring the finish on the beautiful chrome lining these fine shotguns have, i noticed a distinct black ring that looks to hold fouling and does not want to give it up. The rest of the barrel and chamber look and feel like the inside of a glass tube.
One is a M1 and the other is a M4 they both have the same ring in the same spot which is 3" in from the breech (just after the shell). Which leads me to think its just baked on there from firing. Is this fouling and debris etched on to the bore or has the chrome erroded?
The older M1 barrel ring has fouling embeded on the said ring that keeps on coming off as you run a wet patch thru it, the M4 barrel is newer and has no fouling residue coming from it and is still there. Theres no build up that can be felt if you run a pick gently over the area. It just tranistions from smooth to slighty gritty back to smooth.
Called benelli and they have never heard of such a thing and had no real answer for me and said it could of been factory grease that was left in there. He told me to call back tomorrow and talk to tech support before 3pm.
