Guys I have a question for you all. I have a Burris 2x7 LER handgun scope on my Dan Wesson 445 supermag. I do love it, But when I shoot my 445 I get some black dots or fine black lines on the scope when I look through it. But When I shoot it again these mysterious lines or specks move. Then I can keep fireing it and it can go away. It is not NOT on the outside of the scope as I wiped it off and nothing happened, But when I shoot it these marks move.

Any help with what this can be?

Merry X-mas everyone.

Brian
