LP tanke worked with my emag, what?

[Carbon]

anyway last week a nice young fella let me use his tank late during the day. I was low gas and the airfill station had closed. anyway I screwed the tank on not knowing it was an LP. Stangely enough i was able to shoot 3 bps. Im not sure if they were full speed shots, but i had no treouble hitting my targets downfield. odd.

LP tanks generally output around 600-650psi so your E-Mag should fire. Of course if you'd tried to go over those 3bps you would have run into serious problems with shoot down and chuffing.

I shot with a LP tank a few times, it's just slower and less reactive, but the trigger is a lot lighter. Wasn't really a good trade off.

actually most low pressure tanks are 400-450 so they do cause problems.

I guess the one I've had was odd then. 400psi, 600psi you'll have problems either way. I know with the L10 set-up in my E-Mag it wouldn't shoot at all with an input of 400psi.

The 'Problem' with most screw in tanks, regardless of pressure ,is that you really have no idea what pressure it's really putting out as the typical screw in tank rarely puts out what it's supposed to. It's very likey you had one putting out more PSI that assumed.Up around 600psi will fire some L10 Mags depending on the softness of the L10 set up.

[TheTramp]

I agree.

I was using an ASA that had a gauge on the second output hole so it showed the tanks output pressure.

I've put "HP" tanks on there and gotten as low as 650psi instead of the 800-850 they were supposed to have.

Like I said, I used a LP tank and it was in that range as well.

I'm using an adjustable tank now so I can be "sure" I giving my valve the 900psi it likes.

Another thing to watch out for are innacurate gauges. Always use a high quality gauge. Some companies like to skimp on gauges, for example my ACI Bulldog Pressure gauge was ~600 psi lower than what the real pressure was. Now I have a dye gauge and it works great.

I can tell you that Crossfire's are dead-on. I checked both of mine, not to mention the other's I've used.

I can't speak for other manufacturers, however.

My team learned this the hard way, we had a bunch of tanks filled so that we wouldn't have to rush to refill...Well we didnt think that the tanks output pressures were going to be much different and we got 2 hot gun pentalies that day, -10pts each!

[Dayspring]

That shouldn't matter if the air is going through a regulator before it gets to the gun. The reg will take whatever input it sees and brings it down.

[thecavemankevin]

but if the pressure is enought of a difference out from the tank say 200 psi, it can make the velocity climb too. Usually not much, but if you were already on the boarder line then it can push you over.

[Kevmaster]

will a 400psi input fire a ball froma mag? yes. will it have severe shootdown? yes!!

work? yes. well? no!

[abunkerer]

The pressure into the regulators from the tank definately makes a difference.
On that day it happened to an eblade and an impulse, a max-flo and a CP...the variation in tank pressure caused the velocity to go from about avg295 to avg303.
