So I picked up some of these for a very good deal
http://www.ammunitiondepot.com/Precision-Gun-Works-12-Gauge-Exploder-Round-p/pgw1251.htm What would be the legality of filling one with tannerite (very very small amount will fit) and capping it off by glueing a 209 primer on top? Since it's less than a 1/4 ounce of explosive it's not a destructive device correct? Could I make these? |

AFAIK, you're good as long as you stay under the NFA DD ruling of 1/4oz. You're more likely to fall under state laws about tracer or spotter ammunition, which is usually more about wildfire risk than anything else.
And that tiny amount of NH4NO3 and some metal dust won't do squat. You're probably better off with one of the titanium flake spotter mixes. You might be able to figure out a chemistry that works at someplace like Skylighter, or semi-pro fireworks forums. Don't be tempted to use a flash composition mix in these slugs. You'll get hurt badly. They're very shock sensitive, and detonation on firing is a very real possibility. Someone got their hands on a bunch of milsurp 14.5mm M31 artillery trainer projectiles, which are essentially a 20ga shell case. But they've long since sold out. I'm not sure if they were pulldowns someone reloaded, or if they were sold intact as-is. http://www.casr.ca/doc-npp-artillery-trainer.htm A Phillipine's military forum still has some pictures of what the M31 artillery trainer looked like. |

Thanks for the advice AJ. I agree the flash powder is a bit sensitive for this application for most forms (chlorates perclorates and permanganates) but the ammonium nitrate mixture is pretty stable and has actually been used in these slugs by people before with no issues. However I like your point about the magnesium powder. That small amount of flash powder likely won't do much of anything that won't already happen when a slug hits a steel plate but the magnesium or aluminum powder might make for an interesting show... Do you think I'd need the 209 primer to set them off? |

I've decided to leave my flash mixtures for other non firearm related experiments. Does anyone have any ideas on stuff to fill these hollow slugs with? Magnesium and aluminum powder capped with a 209 primer? Fill the cavity with oil, and plug it with a steel ball bearing. If you're gonna eat what you shoot, use a food grade oil. otherwise any thick oil will do. Quite explosive when it hits, depending on the size of the cavity. |

Do you think I'd need the 209 primer to set them off? I had no idea AN/Mg mixes would actually WORK in that small a quantity. I know it's stable and safe as houses, play with a Bic lighter and a hammer all day, and nothing will happen. If others say it works, then go for it! There is the hygroscopic nature of AN, so they'd have to be sealed well if you intended to set aside the loaded slugs for any amount of time, or you'll still get duds. I just assumed a 209 primer and that small of a volume wouldn't have enough mass or set up a supersonic compression wave in the mix like is required for Tannerite/Binary targets. Hell, then throw some bigger Ti or Mg flakes in there and have at it. Metallic Zirconium is awesomely pyrophoric too, you might find someone with shavings for sale, IIRC, that's what they use in the Rafouss .50 BMG APIT.

Several states have laws outlawing exploding ammunition. I'm sure that's true and while I haven't checked my states laws yet (just getting ideas) I live in Texas...and well there's not much we can't legally do here involving firearms and other toys haha. |
