You know these like taliban-antivehicle shots that they make,

I am actually curious about what is the minimum size of an explosively formed penetrator. Does that shit scale down to babby size? Or do they have to be like 3" minimum?

Fluid Dynamics is not my strong suit.

no

I don't think blackpowder would work because the explosion is subsonic. The pressure wave would just push the cone out instead of deforming it.

Great discussion, ending strong I see. Bad start but you made up for it with the PowerPoint

>>32993802
Yes, that subsonic part is something i've been wondering about aswell

>discuss
You asked a question.

Do you want us to answer it, or berate you for making a retarded thread?

Stop putting "discuss" at the end of you posts.

>>32993830
I dont think anyone has the calculations to give a true answer, instead i want them to discuss what they think is right, cunt

Small shaped charges the diameter scale of cartridge casings can be done, search for it on the sciencemadness forums. However, you will need an insensitive high explosive like RDX or HMX. I doubt even semi-stable compounds like PETN could survive the impulse of being shot out of a rifle. Here's a liner someone made by melting all the lead out of a .45 Long Colt bullet.

Ok, not every idea is a great idea that needs to be discussed, some are plain fucking retarded, like yours, so once again. No.

>>32993590
Size? Yes.

Using black powder? No.

Don't like what i want to talk to People about? Then fuck off, noone invited you and your grinchy ass.

>>32993888
I agree

>>32993869
hold on. im sure that someone put lead azide in a bullet, which worked

i'd rather hang around and call you retarded, remember, we're here forever.

With blackpowder you would have to contain the pressure long enough to create a serious bang to get it to work right. Which you just arn't doing in a normal sized firearm.

Some sort of all metal potato gun with some sort of coupling that breaks at a certain PSI to release a saboted round would be possible but would require a stupid beefy housing and significant amount of BP.

The range and accuracy would be abysmal compared to conventional bullets and it'd be woefully ineffective against soft targets. I can't really think of an application.
It'd do everything worse than an EFP contained inside of an explosive projectile, but even HEAT-style ammo in anything smaller than .50 is inefficient compared to regular or AP bullets.

>>32993977
lead azide, like in an explosive bullet? Because normally that stuff is in the primer.

>>32993802
Black powder for propulsion. MANPADS are actually pretty slow. But you need a secondary HE charge, triggered by proximity to form the penetrator.

Altogether a tough engineering job for a rifle or handgun round. Maybe a 12 ga?

>>32993991

a "hybrid" potato gun is almost exactly like what you describe, except it uses a pressurized fuel/air mixture instead of black powder.

Alphabet soup.
