The 8 Penny Shotgun Slug of the Apocalypse - TESTED!

Today we test an interesting 12ga. slug that is simply made out of pennies- but using science. The slug is designed to be ballistically-stabile without any spin at all.

[@Odinfang]

Not only impressive, but rich in potential. You could drill a hole in the stack, shove in a nail and bind it all together with putty. You can cut notches in the Pennie’s for potentially better flight, plus, the way they’re rounded, you could fit wax and shot in a chamber made with 2 pennies for more weight, again drilling a hole through the center to keep the chamber connected to the penny stack.

[@johngray3860]

That gives new meaning to the phase, "Money Shot!"

[@bigharrybushcraft8364]

From now on, if you use hot glue, I think you should be obligated to use some glitter as well! Once the glue cures, you might be able to tap a stainless screw through the nose for a possible penetrator. Also, if you plan to continue testing on this line and want to boost velocity but are worried about flight separation, you might be able to maximize the glue effect by sticking the formed slugs in an Easy-Bake-Oven nose down for a bit to help even out coverage. GREAT video! Thanks guys! Be safe out there.

[@Odinfang]

I’m so proud you cracked the code on using coin currency as ammunition bud. I’d love to see you experiment on other coins. Even unglued, the pennies fly in a great column to mimic a slug. Rounding them like you did desperately needs more experimentation with other metals. I hope some machinists at watching and devising what’s best described here as a rounded disk column load. Edit: after more views and brainstorming, I realize that you could drill a hole through the center of the stack and fit a nail or core inside, using putty to keep it all together. Plus, the way the pennies are rounded, you can also put two together to make a chamber you can fill with wax and shot for more weight, using a nail to again hold it all together.
