I seem to recall that when he measured the wall thickness, it was on the thin side.
You can see the tool marks in these photos.
Fluid steel would have split....
Pete
Larry..........
Could have been an obstruction...?....The damage to the shell casing might have been the result of the exploding metal since the barrel was segmented damascus that was exploding outward, backwards and forwards as evidenced by the curling fractures......?........
At first I thought the split fluid barrel picture was part of the same gun, but they are not the same set of barrels as pointed out by jOe........I also think that the extremely thin wall at the chamber-cone junction accelerated the failure, i.e.-
point of least resistance........but I don't think we will ever know conclusively.........?.........Just glad Randy and his brother were not injured to any extent.....
Best,
