For ever slingshots have been all about the bludgeon affect. Penetration isn’t necessary to hunt. A blow like that will kill a rabbit clean. For penetration use steel shot in a smaller diameter.
Yes absolutely, I know a slingshot mainly kills by blunt force trauma and penetration is just a bonus. And these were just done for fun. :D

I sprained my finger so I've gone with lighter bands & a lighter draw. From 8 fpe down to around 6.5 fpe. Still using 10.5mm lead (7.1g).
Here 6.5 fpe on a soup can filled with water @ 5 yards. Still penetrated 1 side and made a dimple on the other. Made a tiny clean hole, when filled with water.
Oh and the can wasn't braced, same as last time.

Then few more test with empty cans. Braced and not braced.
Empty can 'Braced' against thick blankets behind it. Result was a tearing like effect compared to a clean puncture. Tested twice same effect on empty braced cans. Kitchen utensil Jewellery Automotive lighting Audio equipment Electronic device

Empty 'unbraced' soup can, different result. No penetration but a large dent and it was sent flying back.
Next, filled the can with water and tried the base of the can where I suppose it's structurally stronger. Lead managed to puncture 1 side again with a small clean hole.
