i saw an episode where dog the bounty hunter and his crew rolled up on somebodys job to secure a wanted fugitive. they were all packin a5's with maceballs.

markers and maceballs have been around for awhile.

FUN FACT - The Fabrique Nationale FN303 is powered by a modified Airgun Designs (AGD) Classic valve system.

With this in mind I will shoot and spread some knowledge all on your faces. If the input on the fn303 is roughly 900psi (mag happy) then the internal pressure is probably going to be 350-450 psi as the valve system is basically a regulator in itself. (See Air america, ANS, Flatline, armageddon, etc. regulators are all built the same as a classic automag A.I.R. valve.) The article is a little misguiding in that aspect.

If the fn303 is putting 900psi directly on that pepperball, somebody is going to have a rough day at work. I might be wrong.

My mag is heavier than your mag.
My other mag is lighter than your anything!

please see previous post about pressure alone having ZERO to do with how fast something moves.

I'm familiar, thanks. And I'm not referring to speed, I'm talking about pressure. But my statement involved the fact that the nlweapon is based off the agd classic valve, and with that it mind, if there is IN FACT 900 psi directly behind the projectile, then I don't see the projectile travelling past the barrel tip in one piece. Also, like you stated, without knowing the volume you can't know what the balance of volume to pressure really is. Like I stated before, the article read that "a typical paintball is regulated at approximately 300-500 pounds per square inch, while the ISNLS is regulated at approximately 900 PSI," which can easily mean that the input pressure (past the regulator) of most paintball markers is between 300 and 500 psi, roughly accurate. The 900 psi stated in the article sounds pretty standard if you are familiar with high pressure markers, maybe you have heard of a Tippmann? how about a Spyder? what about an early Autococker? Automag? Phantom? Let me know if any of these ring a bell, all high pressure markers that would be more than happy to accept 900 psi (since 800 psi is the standard output of ANY CO2 cylinder). Most high pressure markers operate at 750 psi and up, especially automags, which are rated for 3000 psi input pressure, compare that to the 900psi in the article, and you get? nothing. The input pressure isn't going to make a difference from 750psi-3000psi, as long as its regulated by the valve. Valve output pressure, likely to be 350-450 maybe more depending on the valve's velocity setting and flash chamber/firing can volume.

It comes down to the fact that the article isn't written clearly enough for the common folk. Any common paintball marker could shoot a finned bullet shaped projectile 100 meters, its the round ones that are the trick.

Ill go along w/ early cockers, tippmanns, spyders, phantoms, nelsons etc running at bottle pressure, but im pretty sure that mags reg the input pressure down to 350 ish.. that is what the rear reg is for, and the little grenade spring doing the work.

Being in the Army and as an MP and a corrections guy I have used the 303 many times and are defiantly not normal no hopper, runs on a drum style loader and the rounds are ridiculously hard.l and shaped more like a slug than a paintball. For all wondering yes it hurts too!!!!!!!! No joke if you wanna use it you have to be shot by it same as a taser!!! Sometimes I hate my job!

Like I said, their air source is likely regulated at 900psi into the launcher, which the valve will regulate down again, the actual output on ball pressure is likely going to be 350-450ish.

Someone else noted that a 'mag is basically a regulator. True enough.

That particular reg design uses a piston and a spring; presuming that the housing/fittings are pressure-rated to the correct specs, modifying the piston/spring arrangement can yield much higher output pressures.

This is one reason why several different training/LE/NL systems have been based on the A.I.R.
