As for the ammunition it self if launched as an inderect fire, you could insert a parachute to slow the fall of it either all the way down or low enough to let it fall freely at a safe speed for its weight. You could also include in the ammunition a system that would make it "detonate" so that it spreads BB all over an area. This last system, combined with a parachute would render the ammo pretty much safe, don't you think?
I know this seems complicated but for safety sake I believe it is doable.
It's definatly an Idea... we'd need to increas the power output of the Co2 Rocket to get it high enough... but we were gonna need to do that anyways. As it is it more resembles a recoiless rifle (keep in mind this is all still in the testing stages.)

I'm trying to think of a way to load multiple Co2 Cartriges into one projectile so that they provide more power. The problem isn't fitting the Cartridges... it's setting all the F**king things off at once!

Here's some constructive critisism

This is the kinetic energy formula

Kinetic Energy (joules)= 0.00004645*m*vē
m = mass in grams
v = velocity fps

My L96 fires a 0.36 bb at 400fps. At point blank range, that's an impact energy of 2.67 J. That would hurt a great deal.

What's the mass and exit velocity of the projectile (and kinetic energy)?
What's the safe shooting distance?

ok currently it only has an effective range of 20 feet (if you can get it to fire) and right now in its state it could only be used as an anti-armour weapon. I'm attempting to give the round some sort of spin like rifling (but its way to hard carve out rifling inside the tube), so i could use some help on that right now. Once we get the round to move then I'll start working on angle regulators and dessent speed regulators(ie. parachute).

p.s. I'm sorry for my bad grammer in my first post, I just didn't really think about it mattering too much but now I'll do my best to reach your par.




EDIT: And it is far away from completion so I admit it is still quite dangerouse but it shall not be fired at anybody or anywhere near anybody until it is completed and proven safe!! SO PLEASE STOP ACTING LIKE A BROKEN RECORD PLAYER AND REPEATING THAT!!

I could definatly see that carving all those "rifiling" races in the tube could be a pain in the butt. How about angling the fins and grooving the projectile to induce the spin similar to those nerf footballs? Just a thought

Instead of useing small Co2 catridges could you incorporate a larger Co2 Cartidge into the frame with a trigger that allows required air out on each pull.

Then you have recycleable Co2 and no worries about co2 catridge hurting anyone.
Cut a nerf football in half attach something like half a 600ml pop bottle attached to that. Then fill with bbs/flour whatever. not sure how you would incorporate parachute in this design though. Sounds crude but might work..

would probably have to put a bit of weight in half of nose of rocket though(nerf)

Maybee use something in that rocket that reacts to being shot so it seperate top and bottom in mid flight. thus deploying parachute attached to each end of rocket(inside)
and pellets.

One 12 gram Co2 Cartrige + heavy duty, vertical spin upon leaving the barrel + launch difficulties + straight line firing, not on a upward angle = 20 foot effective range so far. That's pretty good considering everything going against it.

Once we get the round flying straight and true that will help. Add some more Co2 cartriges, and you've got more range and power. Aim it on a 45 degree angle and you have more range... need I go on?

Once again I call attention to the fact these are test firings to see if we can get it to launch at all. Accuracy, range, power and most importantly saftey come later we have to be able to reliably launch the damn thing first.

So it dosen't go very far and dosent sound like it has much impact. I still like the idea.

those "air hogs" toy planes can easily be modified into a rocket, then all you have to do is find a way to explode something on impact. if you can get around to it before me than knock yourself out. when im done my other projects i will be working on that.

the only problems with that is that each shot would be less as powerfull than the last and I don't feel safe having something I made super pressurised with air (may go boom) so this is the safest and easiest way


I'm currently desining a round with a shell that would not require the CO2 cartriages to be flying through the air (so you can all feel safe when you see this at a game)
this is what i got so far...

I belive i have figured out a way to rifle the barrel of my arty (thats right i'm a genius) My father is a tile layer and he has a mashine for mixing the tile glue, which is long and narrow enough for this project. HOOWAH!! this is really lookin like its comin together.

We have officially decided that if and when this piece is finished, it shall be called the "Killo Ma-Wacker".

It occurred to me that that new shell design A) isn't really rocket propelled (because the propellant is in the shell casing) and B) it would probably have recoil, though we don't know how much.

Depending on the amount of recoil, we MAY be able to convert it to fire semi-auto. Keep in mind that is a MAYBE as in we don't know and it only a theory so far. We will see what we can do once we have the first model fully functional.

Geezuz Xrist people!
Just use fucking potato gun and some BBs wrapped in paper as the projectile
I can launch a 2" diameter potato about 100 meters at 45 degree angle. At 90 degree angle it goes high enough so i cant see it anymore. Stuff it with a couple handfulls of BBs in a sabbot and there you go. Simple and easy.
Oh, almost forgot, use hair spray for the propelant and BBQ igniter (spark) for the igniter. End can unsweres and recharges with hair spray. Dont try to over think things

Where's the fun in that?

Also, I'm sure your not the only person to think of that, and that the Idea has been dismissed for saftey reasons.
