I believe the frame broke when he hit it on a metal hook hanger and the center biscuit moved or fell out, which threw his shot off. Apparently he had one of the original WB that were made of some kind of compound plastic. I know now they are made of a composite metal or aluminum which mine is. He rigged it with a sewing kit somehow, but his grouping was still 7" at 15 yds, and shot to the right. Luckily thats all he needed to fill his cow tag.
