You could try it. I dont know what would happen...probably nothing. However...Nitrogen is completely inert, dry, and will not combust...its about as safe as can be.

Also...I guess you would have to take the tank to a Scuba place to get them filled? What does that cost and what pressure will they fill too?

A 10 lb nitrogen bottle will be filled at a gas supply store for about $5-9. I have a larger nitrogen bottle and get that filled for like $19 and then service my own pusher bottle. I can go through three 15 lb nitrous bottles before it needs to be exhanged for another. Best way would to get your own BIG nitrogen tank and service your own small tanks. Then when the big tank is done...you just go exchange them.


May sound like a bit more of a PITA....but you will make up for it in NOT waiting around in the pits for your bottle to warm up..lol.

 

cool man, see you there. im going for sure.

 

I'll throw this out there for thought.

High end paintball markers use nitrogen for their gas source. For example, mine has a small carbon fiber bottle with a built in regulator that I set in the 900 psi range to achieve the desired velocity. Regulator creep (thus velocity) is non existent and the small bottles are capable being charged to 3,000 or 4,500 psi. The newer tech markers a capable of 20+ ***** per second rates of fire, so stable regulation is critical.

Pros...... compact, lightweight, and stable pressure regulation.
Cons.... need access to a paintball field/store for refills at those pressures.

Cost for the C/F bottles vary from $300-$400 depending on the size and pressure capability. Here's a link to one company's offerings, but there are several that make them. http://www.airamerica.com/store/
