Automatic hybrid cannon

This is my idea for an automatic cannon, it’s got quite a few bugs which I’ll list at the end.
It’s official title: Judgment Arms 200cal. automatic hybrid cannon model XM000 or A.H.C.XM000

First I’ve got to tell you what it shoots or otherwise you’ll be very confused. It uses “cased” ammunition made out of 1.25inch SCH40 PVC with an end cap on one and a burst disk on the other. The end cap will have a brass or copper ring about 1/2inch wide on it, and what ever I get to hold the burst disk in will have a brass/copper ring about 5 inches wide on it, the reason it’s so long is because it holds the projectile in it. Attached to the copper/brass rings will be the spark gap. The case is pressurized and filled with propane and acts like the combustion chamber on any other hybrid. The projectile will be ether a paint grenade which is my preference but if they won’t work for one reason or another I’ll use NERF rocket/foot ball/dart/thingies.
Ok now for the gun:
The gun itself is basically a tube, a piece of 2inch SCH40 PVC which is the barrel and most, or at least part, of the receiver. The bolt would be 1.25ich SCH40 PVC because it fits inside 2inch SCH40 PVC. The breach has brass/copper rings which correspond with the ring on the case, the rings receive continues electricity from a tazer. The gun firers from an “open bolt”, which means the bolt is normally open, when you squeeze the trigger the bolt closes pulling a round out of the magazine, pushing it in the breach where the brass/copper rings meet up completing the circuit generating a spark which ignites the propane firing the cannon, some of the gasses from combustion are channeled through a gas tube close to the muzzle to move a small piston which unlocks the breach allowing it to fly open ejecting the spent case. the gas operated idea may not work if it doesn’t plan B is pretty much the same except when it fires the recoil open the bolt. The extractors are shone in the one of the pics. The ejector is the next round in the magazine, which works as fallows. The magazine will be made out of plywood, as wood is the easiest material for me to work, it will be a five round magazine as anything bigger would be to balky, the rounds will stick up a little in the front, which acts as an extractor…as I type this it occurs to me that this would not work as there would not be enough force to throw the round clear…
That’s about all I can think of.
The bugs and problems that need to be worked out:
1.ejector, as of now I do not have an idea on what to do about this problem.
2.ammo, does anybody know the average OD of a “Pod Rocket”, or of any paint grenades that fit in 2inch SCH40 PVC?
3.the “mix” I’m thinking something like 2X or 2.5X.

This is my design DO NOT COPY IT AND CLAIM IT AS YOU OWN!!!!! If you deiced to claim this as yours just be warned I don’t use the court system, and I like turkey hunting…

There will be more I’ve got a lot of bug to work out but as for what I’ve got so far, whatdoyathink?
