That's hilarious. A tumbling dowel pin at 200 feet/sec. That might not
even break skin.
 
Imagine that in a battle with even a .22 rifle. A .22LR is about 1200
f/sec and the rounds arrive pointy-end first.

It reminds me of a rail gun. Gunpowder packs a lot more energy per
volume or mass than capacitors. A lot.

As gasoline packs a lot more energy than batteries.

I wonder why that animal injector thing doesn't just use a spring. I
have a blood sample lancet thing that has a spring; it works fine.
It's cheap and no batteries are required.
