Mortar Round Idea

[ScottCollins]

So as you may have guessed by the title of this thread, this is a concept for a mortar round. (Drawn in Microsoft Paint, don't judge.)
If you can't understand the doodles of a half asleep teenager, I will translate.
My idea, is to place a percussion cap mechanism inside a toilet paper tube. The mechanism itself would be placed into a plastic box or tube to prevent fire. The little black thing at the bottom would just be a small item like a screw, something rounded. That would then be attached to a piece of gruff material. Then using a bundle of strike anywhere matches, the piece would push up and light the match bundle. That in turn would set off the fuses attached to a small firework and set that off. Thus in turn, destroying the plastic surrounding it and sending the bb's off in every direction! I haven't figured out the propulsion yet so that's still in the works.
Tell me what you think guys. (Very entertaining now that I see how silly it looks. Looked a lot cooler in my head...)

Cool. Typically to work consistently I would think it would need to strike hard ground and fins (as shown) are critical to control flight but very hard to manage when being fired from a tube. Spring activated upon leaving the tube perhaps? Designing pyro weapons that are safe, don't produce fire dangers and can still effectively distribute BBs are quite hard to pull off but would really add a lot.

I was recently toying with the idea to use a similar method to replicate mortar strikes.

Same concept, but using a .22 blank. The tip of the round, on impact would push in and using a firing pin, would set off a .22 blank, that faces towards the rear of the round. The base would be empty, to allow flour or some powder to be added for the blank to poof out when it goes off. It would produce both a small smoke cloud and a bang on impact, and it could easily be retrieved reloaded and reused

[ScottCollins]

That's a good idea but I think for Airsoft purposes, its best to have bbs. That's why I don't make baking soda landmines. They just don't feel in the spirit of Airsoft.

I always thought if you could somehow wrap up BBs in like tinfoil or something without it tearing while handling, but exploding on impact, you could have anti personal disposable shells.

But then you'd need a lot of compressed air, unless you make them small and/or light.

I like to see both BBs and a dust/ smoke report. The challenge of course if you create your effect with powdered explosives there is a fine line behind enough ordance to create adequate dispersal without being dangerous. If compressed gasses are used there can be a shroud of Bbs and fine powder (Talc or dried cement work well). As with both the detonation method is the key. Solt ground seldom provides enough resistance for most gravity inspired impacts. The 22 shell definitely requires some striking velocity and probably more then you'll get from a long range plunging shot.

As with all of these things keeping it simple is the best way to insure SOMETHING is used and at this point the howler footballs are pretty cool and function quite well.

My favorite and something we use at RECONDO a lot are the 4th of July Mortar rounds. They make an impressive report upon launch, fly a considerable distance and can be angled and fired with timing that creates very impressive air bursts 10 to 20 feet over your target. With goggle and normal helmets, uniforms etc they have proved quite safe (albeit quite terrifying) although I do have a few tiny sing hole in my nam geat.

Mounting the supplied lanch tubes inside a proper replica mortar provides a very good look. Visually both day and night these look great. The effect is rather like Hite phosphorous in day light.

Not really related except it's a guy fooling around with ways to make popping sounds. Pretty funny:

Excellent idea for the primer but as shown to discharge it needs to strike a solid surface with a lot of inertia.

[roma]

For impact detonation you can use inertial system with small plastic ball, soft spring and plastic percussion-cap, like in TAG innovation system rounds.

[ssgjoe]

Timed detonations could work too...if you know how to do it right.

I'm thinking the best way to do it is either to make each round, cheap, reliable and expendable, or make them trackable (ribbon), reliable and reloadable. Making anything more complicated than it needs to be will drive up the cost to use the mortar, and make your shots less reliable to go off on impact/timing.

So I saw something and I thought it could apply here. If you were to make a mortar that fired 40mm shells, These would be an excellent mortar round: airsoftpyrotechnics.com/airsoft-pyrotechnics-products/reaper-starter-kit-detail#.U7s_pfldXD8 The two cons that I see are that they are pretty costly, and they are on a 4 second timer.

I use them for my M7 garand grenade launcher. They are pretty good but if I make a big angle to fire at long distance it explode in the air. You can see it here (video at the end) ww2aa.proboards.com/thread/9386/m7-grenade-launcher-m1-garand
Now we are looking for mortar rounds for our new 60mm mortar as well. But I think for mortar round it is too small in explode.

[shiftysgarand]

I'm guessing you could mess with the timer to get it to explode around the time it hits the ground and not in the air. The cost problem doesn't go away though. Also, I think airsoft innovations is planning on releasing an impact detonated 40mm grenade that could be useful.

[insterburger]

I think the problem with impact-detonated rounds goes back to what 2ndBat said. The vast majority of our games are woodland, and in the future if we're playing in the NE in open fields, they will be grown over with grass. In both cases, there are plenty of things to break the fall, be they branches, shrubs, dried leaves, or tall grass. Anything that could successfully cut through all that clutter would have to be heavy enough to be a real liability due to potentially dangerous weight if it hit someone directly. All in all, I could see an impact-detonated mortar round being more frustrating than useful.

[2nd Bat]

It is fun to dream and fantasize about what could be and i put this discussion mostly into those camps. I think Insterberger you and I are among the few with functional nerf mortars capable of being used in an event. Those creations are tough enough! Still sometimes dreams come to fruition and seemingly insurmountable challenges are overcome.

In the case of functional, safe and reliable exploding rounds that disperse Bbs and are somehow affordable, I'd be all for it. For now, I find the howler nerf rockets and Big Eds multiple tennis ball cannons to be quite effective.

They have made it already but it is not reliable, because the grenades are very light and require rigid surface to explode.
