Hello I build slingshots

Hello im tom and im 12. I build slingshots that are extremely powerful. Alot of you may think of a slingshot as a little boy toy that cant do much more then break a window. But slingshots are extremely powerful. The ones for hunting produce around 100-150 joules of energy. Those ones have around 50 to 75 pound draw weight. Enough to kill game like deer and send a ball bearing completely through an armadillo. Heres some of my slingshot videos.

I googled it for the conversion rate. 1 joule = about .7377 foot/lbs, so 150 joules is around 110 ft/lbs. A bit less than a 38 grain .22lr projectile moving 1260 fps (134 ft/lbs).


A projectile moving at around 200 fps with around the same amount of joules will cause allot more damage :yuno: duhhhhhhhhhhhhhhhhhhh

Probably enough joules there to bring down a small flying aircraft..some serious ball bearings.

I'm a bit rusty on the whole slingshot terminal ballistics thing you have going on.

Got a link to any verified tests?

Well tests coming soon but here is some logic. A 22 round withholding 130 joules of energy has the same amount of penetration power as a 30mm steel ball with the same amount of energy. But it would cause more damage than a 22 because it has more surface area. Causeing more 6x more damage then a 22 because a 22 bullet is 5mm.
