Ok, so i might just be paranoid because I'm new to owning guns but i got my 870 the other day and went to clean it before i shot for the first time. I put about 20 of the patches down the barrel and they kept coming out dirty. I was using redhead gun cleaner that came in a cleaning kit i picked up. when i look down the barrel i can see i ring of dirt/junk (not exactly sure what it is because i haven't shot the gun yet). I guess my question is is this something i should be worried about? I am going to go back tomorrow and pick up more patches and I have run my bronze brush through it a few times to try and break up what ever is in there a little. sorry if this is a newbie question.
I tried to get some pictures of the inside of the barrel so you can see what I'm talking about, but they did not come out great.
