37mm Tannerite?

I do not know anything about the legal ramifications, nor will I suggest any legal advice, nor what I say could be construed as legal advice.
That being said, I have thought about similar things. I do not know at what point tannerite becomes a explosive (or if it actually legally ever becomes a explosive). I would "think" that it never is a legal explosive based on the fact that it would then be a felony to pop off some (i do not know either if a specific amount changes the classification).
Tannerites reaction is started by high pressure shock. I do not know if the firing of the grenade would detonate it or not (I would guess not) but the contact I would most certainly think would not detonate. I can think of multiple mechanical devices that may or may not work to detonate it, but I think that they would be more trouble then they are worth.
What I would think the best method would possibly be to go, is research what exactly constitutes a firework, and find out if you can classify a fused black powder shell as a firework. I do not know what the legalities of a remote discharged black powder shell would be. A magnesium strip fuse that is ignited off of the 37mm shell (with a wadding between the propellant and the charge). It would be more of a distance fuse then a contact fuse. But hey, you could add metals to make it a cool color and what!

Just thinking things through, (again, no legal advice here). I cant remember what your m37 was classified as, is it a dd or a shotgun (sbs?)? I do not know if this matters, as I "think" it more matters what you launch then how... thinking about can cannons.
Just had a thought... you need a dragons breath shot... please post a picture!!!

why dont you shoot the tannerite in a pile with a concussion 37mm round, a direct impact should trigger your desired results

This. It’s not going to work. Bad idea. You could increase the launch charge but it’ll likely blow your hand off before blowing up a target.

Been getting interested in booms and thinking about 37mm. As was mentioned, any HE above 1.3 grams makes it a DD if launched. Tannerite/ammonal is a HE. So no no to launch, transport, sell mixed, the whole bit. It is also pretty insensitive (there are ways to sensitize) and will not do anything more on impact then fertilize your range.

How to legally have fun? Easy!
First, it is your responsibility to know your state and federal laws obviously. Also if you hurt anybody or anything, thats on you. Also I would NOT recommend using 3d printed launchers as a hang fire can be a life changing experience.

All of that being said. Here is a excellent video to download on how to make reliable fuses (dude in video has a different application for it)

A 3d printed hull could use a similar fuse to the one in the video. Would use a two piece shell that the noze screws on to. The shell can be filled with a potassium perchlorate/dark aluminum (70/30) mix. It is relatively insensetive as far as flash powders go. I would not recommend making large amounts. Flash powder is not a HE. Coupled with a time fuse (time it to land and sit before going) you will get a excellent report, and very bright flash.
Flash powder mishandled can be very dangerous! Reloading is dangerous! Life is dangerous! It is safer to not have fun.
Anyways, theres some ideas.
Oh, you can buy commercial novelty 37mm "flash bang" rounds that are this exact thing.
