Just out of curiosity is your barrel polished on your 3500? I'm going to range Saturday with mine...with 3.5" Longbeard 6's. All I have for chokes is a Comp N Choke XXX .650 and Ballistic Specialties Angle Port .650....anxious to see how they do. I replaced barrel last year with a 24" and need to polish it before I go out.
