ok, so this is my first post in a long while. but i was wondering if we had made any advancements of incendiary rounds, worked them out and found a way?

Check out the "slinging fireworks" thread:)

We have had a few attempts, luckily no one got killed or maimed.  That's not a joke, improvised munitions are unfrikkingbelievably dangerous.  A cool and safe alternative is taping a piece of fuse to a rock or tennis ball.  It doesn't blow up but it can still catch things on fire if you aren't careful.

I found something,that works surprisingly,as it looks cheap.
 
You take ~7 pieces of 3-4mm steel BB's and pack them in 1 layer of alu foil,accompanied with 9 "shots" of cap gun powder. Just press the foil slightly,also don't worry the caps need a sharp shock or a very strong pressure to explode.

Then you take this small stuffed  foil ball ,and place it inside any powder you wish,and inside any casing you wish.
I tested 2 of these inside a ceramic egg and both worked excellently,ignited upon impact,even though the soil was very moist and soft.
I used a smoke powder,made a great spotter round.

I wouldn't do this with a exp. powder either. So i stick with smoke mix.

Remember the old "snap cap/fun snap" fireworks?- little wads of wax paper with a bit of sand and fulminate in them?  Kept dry, by, say- flash paper, then plastic wrap, you could sling a burrito-sized package (napalm filled ziplok bag, wrapped with flashpaper, ignited by snap caps, or a fuze).  The caps hit something hard, ignite the paper, which burns through the plastic, and ignites the gelled gasoline (dissolve styrofoam in gas- add powdered metal and oxidizers for greater effects).
Throwing "fireworks" is for entertainment.  Throwing an "incendiary" is for causing damage with heat and flame.

Dan, we can't discount chemical reaction incendiaries.  There are many different recipes, most of them with commonly available ingredients.  I won't list any of them in detail here, but they really aren't hard to find on the internet if you know how to look.  My personal favorite is a binary concoction of stop juice and recreational algicide...I won't spoon-feed anyone anything more than this though.

I have been using smoke bombs (firework store) in paintball and slinging them around the battlefield. But I am very careful of this only slinging when im positive it is clear. If im not I toss them.
