Saboted canister shell help
Posted: Thu Jun 22, 2017 7:38 am
I want to create a sort of "canister" or "grapeshot" round for my cartridge combustion Spud Howitzer that can rain paintballs at a distance.
While I know that I could probably just fill a paper cup with paintballs and put it behind a wad of some sort, I want to get better performance, ideally a spread that is effective at a distance of 100 feet.
To test this, I have come up with this shell. It's essentially a wad made of EVA foam with a paper disk that is cut and folded (as in the diagram) and filled with paintballs. To keep this sabot together, a couple loosely tied pieces of yarn are wrapped around the middle and top (these will hopefully simply slide off in the barrel during firing). The top of the sabot has a tissue stuffed in it to prevent paintballs from falling out prior to firing, it too will fall off during firing with the sabot and yarn due to it's light weight.
Is this an effective design and is it any better than just a bunch of paintballs wrapped in a paper towel shoved down the barrel?
