Last year I sent Briley my barrel from an Ithaca SKB XL 900 20ga. semi-auto and had them put choke tubes in. It has a extra thin barrel and they were the only ones that could do it. This gun shoots 3" shells and I want to use it for turkey hunting. I've had this gun for 20 years and shot lots of skeet, doves, woodcock, rabbits. It has always been a POA shotgun. It had a IM cylinder choke. I never shot the gun until today and tried to pattern it with Briley's extra full lead choke and Federal 3" 1-5/16 oz. #4 and #6. The center of the pattern is a foot high and a foot right @ 35 yards. I raised the front bead, which is fiber optic up an 1/8" inch and the center is still 6 + inches high. Cant go any more. Have aim a foot right to get it on center. I dont know what to do. Should I call Briley and see what they say or should I try to find someone to bend the barrel? Figured this would be a place to start. Thanks, Mike
