I want to try my hand at making small-stun grenade type devices that make a really bright flash... I was thinking about having a HE core (probably AP) surrounded by Mg powder.
I'm kinda worried about the HE blowing away all the oxygen so the magnesium can't ignite, would mixing in a oxidiser (I'm thinking about using Potassium Permanganate) fix this?
So then I'd have a KMnO4/Mg Flash powder surrounding a small HE core to disperse and ignite it.. would this work? Is it similar to 'proper' stun grenades?
Would just the flash by itself work? Or do you still think I should have a high-explosive to set it off all at once?

Personally i would never use any high explosive compound for anything like this. Using only flash which is aluminum /perchlorate based flash charge would not only be cheaper than a mg/ perchlorate flash charge, but it would also be slightly more stable. High explosives owuld be much more dangerous to not only the maker but to anyone around when it goes off as high explosives would propel objects WAY too fast which could cause some quite serious injuries.
I have actually started a thread about stun grenades which goes by the same title. i've posted pictures and all of a stun grenade which i constructed.

An HE would just scatter your powder away. It might even detonate it, depending upon what the 'flash mix' of which you are speaking was. If you search the web you will see that chlorates/perchlorates can be detonated when sensetised by something such as a metal powder. So it's the shitter for that idea.
In order for this fuel combustion idea to work, you would need the explosive itself to detonate with a positive oxygen balance. NG does that for example, but you dont want to use that either.
Straight flash can still propel objects fast enough to kill, so why not forget this idea entirely and do something less likely to get you put in jail.

proper stun grenades use either a detonator to propel the rubber fragments, or a very small flash charge according to the 2 stun grenade patents which ive read. Still, using a stun grenade for anything more than experimentation (what i did) would be a bad idea.
Why not just make a flash bang? I'm going to assume that you meant a flash bang which doesnt propel anything more than light and noise though. Am i correct in this assumption? If that was the case, then drilling holes in a extremely thick steel casing which had a thin paper liner inside to cover the holes and then filling the case with flash powder would make for a flash bang. It would emit a great deal of light and a pretty good bit of noise. Please do tell if you meant a "flash bang" when you made this thread though. If you were to make one of these then you MUST have the holes large enough to let out all of the pressure or you would simply have a frag grenade. I dont remember what exactly the dimensions of police and military flash bangs are, but I do remember that the cases were around 1 centimeter thich, they were octagonal shaped, and i "think" that there were 5 holes on each face of the grenade which were again i "think" 3/8ths of an inch i diameter. Ill see if i can dig up my information about military grenades later tonight. The most common flash mixture used in flash grenades IIRC was 70:30, Potassium Perchlorate: Aluminum

Yes, I did mean flashbang actually. Thanks for that, if anyone could give information on the best comps and dimensions to use that would be awesome.
