Actually Chops, it was caused by shooting total of 4 cartridges of 1 5/8 oz. #4, 3" Bismuth loads @ ~ 1250fps. These loads, I find out, generate too much "momentum". Caused by too large of shot with too much velocity going through too tight of a constriction. It could have been any non-toxic or even lead shot if that load had too much momentum.
