Yes, that would be great. Or a machine that can track the entire flight of the sling bullet. Pro baseball has such a machine. I know, I interviewed with the company in Scottsdale, AZ. All the teams use it.

I gave my sling the rabbit test. Head and hind legs remain, minus any connection, and well separated. That is enough power for hunting.

So, what exactly is the "Rabbit Test?" knowing a bit more about it might be helpful.

Also, I don't doubt there's enough power in a sling for hunting, I just doubt it's the same as a .45ACP.

I wish the machines didn't cost so much, because they would be a great tool for studying the sling. If I can afford it in future, I'm going to try to get a radar chronograph and see what I can do with it to get some good data.

The referred to "Rabbit test" was hitting a rabbit with a stone from a sling. Apparently it was done with a very long sling and a variatio n of the piroutte technique.

Best radar chronograph for the money. Timpa said he's used one to measure the speed of an air rifle. I've used it for small stones from a sling with no issues. I think the cheaper version (no smart phone connection) is roughly $300. There are cheaper ones (e.g. Bushnell), but I've seen poor reviews from them.
