Interesting. Do you have any info on what is required to stun and/or kill various small animals in terms of ft-lbs of force, and velocity to penetrate to the organs of the animals?
I have seen the Pocket Slingshot, the one that uses a closed end rubber tube attached to a ring that seems to work very well. I have made simple versions of this using balloons and large bottle caps. They work, but the balloons do not last too long, as they are a fraction of the thickness of the Pocket Slingshot tube.
They are also easy to adapt to use arrows with modified nocks. I know some commercial slingshots have attachments to allow the use of arrows, as well.
I had a decent slingshot when I was a child but never gained much skill with it. I simply did not, and still do not, have the eye hand coordination to be successful. And now, unfortunately, with my left arm and elbow so weak, I cannot support a slingshot in a proper grip. The DIY Pocket Rocket, since I can hold it in a manner that does not require me to hold out my left arm and support the weight, which is minor, or resist the pull with the arm extended. I can hold it down near my waist and brace my left arm. Though I cannot sight it that way, at least I can shoot it. And, I will say, I have decent accuracy that way. Though nothing compared to someone that can hold one conventionally.
Good video (except for the wind), beorn. Useful information and has convinced me to get one of the Pocket Slingshots at some point to put in my reserve equipment kit. Even if I am not effective with it, there is a good chance someone with me would be.
Thanks for the information.
Just my opinion.
