actually I agree on all points:) I really can't see how this item or the earlier diagrams from the shipwreck sight would hold together, unless the charge was really small like for 100 yard distance, basically barely clearing the cannon. , the pictures I've seen of sliding bar shot look too fragile to work also. Overall not a good design. I think even the chain shot flew apart alot of the time, which was sturdier. By similar to the star shot, I ment segmented and designed to seperate and fly apart , which is a little different from chain which loaded 2 balls. Looks like by the CW they had stopped all 2+ piece loaded ideas, IE star shot, chain, etc. must just have not worked well. I can only think of the hot shot which was still used as a 2 piece load, and it wasn't to double the damage, but more of a spacer. The earlier projectiles shows they were always experimenting though, still neet to read about:). It there a book on earlier projectiles?
