Making a hollow projectile from craft foam and using "spent" bb's from an indoor airsoft place is probably the most managable thing, as the foam is cheap and the bb's are usually free as they usually get swept up and go in the garbage. Oh and basically sticking with honour system. As well the very idea of using golf balls and tennis balls is absolutely ridiculous, you will seriously harm or even kill someone doing that. Also the bb shower idea is another alternative.

Anyone contemplating building mortar ammunition needs to keep one simple concept at the forefront of their design - would this hurt if it hit someone's bare head at 100 fps? Something tells me shower grenades, Tornados, and golf balls do not fit that criteria.

Honestly, I've seen several airsoft mortars in several games. They are a novelty and always will be. You cannot make this a practical and useful weapon in the same manner the military has because you have target safety to consider, and consider heavily. Real mortars tend not to have that problem.

Remember people, it's a game.

Its a little more footwork but why not divide the playing area into a grid. You can use a faux mortar and then target a grid and an admin can decide the casualties. Not as fun as pyro or firing things, but its simple and cost effective.

Difficult to administrate because you'd need clearly defined grids or areas that you can define with boundaries. Once you pick the area you have to send admins there and it's possible by the time everyone sees you coming, they've all ran somewhere else to avoid being killed.

It's an interesting suggestion; just playing devil's advocate. I tend to take ideas and think of why they wouldn't work rather than how they could, because if life has taught me anything is that somehow, someone will always find a way to fuck something up.

Really?

*4 guys walk through a forest
Admin: ugh sorry guys mortar just went off your all dead, I guess you all have to walk back to respawn now.

And how much would that hurt if you hit somebody with it?

Your talking about something with a Gas cartridge and firing pin on the bottom.

You might as well be launching lawn darts!

Styrofoam cups and BB's.

End of discussion.

You're not going to come up with a disposable "revolutionary mortar round" that will be cost effective... and no one wants to go retrieve mortar rounds.


Also, for anyone that's interested I'm able to build these things in a wide assortment of configurations... I'm currently working on one that uses the AI propane adapter and pressurized propane as a propellant :)

Just need to sell the old version first to make enough funding for the new one.

out of pvc pipe and using styrofoam as ammunition

static = spark
spark + propane = PVC pipe bomb

Why not get a metal tube, and a 40 mm airsoft shower grenade shell.

take a bottom plate and weld a small "pin" in the centre.
Weld the plate so the bottom pit is facing inside the tube pretty dead centre.

Take the grenade shell and use a grinder to grind off the "lip"

Once completed, just fill up the grenade shell, drop it in, it slides down... the pin inside triggers the shell to go off and BOOM.... a blast of bb's raining down.

Good thing the materials I'm using crack instead of splintering.

You mean like this?

Range isn't really that good.

Instead of a mortar why don't you build a small field gun or Recoilless rifle. Fire a spread of bb's instead one one shell so it would be kind of like a large shotgun. It'll make a Better Anti personal weapon anyway. The bb's can be held in a cartridges to ease loading.

How about a potato cannon just run it off hairspray Potato cannon plans are all over the internet.

Demco11: Way too expensive for something that'll only fire BBs less than a hundred feet.

Tennis balls are nothing more than two-inch diameter BBs. In testing, they didn't hurt any more than a 6mm BB at 400fps. If you are that worried, best start wearing a helmet.

Ever try to hit someone with a tennis ball from 600 feet? lol
Mortars are dangerous, we've got one that will peel the bark off an oak tree using 300g styrofoam projectiles
