after cleaning i always look down the barrel just to check it is clean and shinny. any way about half down there is what looks like a small short thread or fiber or lint that just wont budge with a bore snake, brush, or swab. i tried to take a picture to show you but it didn't work out all. so im hopping to just take it to the range and and maybe it will come out next time? BTW this is a small, small speck of lint or something. i had to look pretty hard to even see it. this isn't the first time this has happened to me. does this occur regularly with you guys? or do you get a perfect tube after cleaning every time? does it even matter? should i be concerned?
