It's not that I like being mysterious, it's just that spudguns are of dubious legality here at best so I don't like to attract undue attention to myself.

The problem with batteries is that even if you create a rectangular magazine in which they fit exactly, the fact that they have a raised positive terminal means that air will still flow past it.


But a verticle mag will have suction without a constant flow? I have had this problem with verticle mags and paint balls, there's enough air to create suction and shoot 2-4 PB's from my paintball gun which is just two small FE's(chamber) and a solenoid valve.

Yeah, verticle fed, holds about 6 PB's. It connects to the barrel in a tee, but I feed the barrel through the tee so the PB goes straight into the barrel.

That would be a negative. :P
The hole in the barrel where the PB falls into is usually enough to hold it in place if I point the barrel at the ground, so I didn't bother with one.
