Took my bird last year with an older square back 390, 665 constriction and LB XR'S in 5's last spring. Similar devastating results. We all like em close but too close can be a problem too. My son's first gobbler was taken at 11 yds. He didn't understand at the time why I was so excited. When back at the public land parking area I safely hung a target and had him shoot another @ 10 yards. Then he understood. Absolute golf ball sized pattern.......and that's way before they came out LB XR'S. I always thought an o/u would be great, choked super tight and the other wide open, but really like my Beretta and it is not finicky at all. Feed it anything and it just eats.
