Two things, First, LP is a buzzword. A confusing one at that. The truth is, the way the term "LP" is being used nowadays, it means almost nothing. And yet people cling to it. Forget it, erase the term from your mind. Relax and breath deep. What is it you want? Do you really care what the pressure is inside? Should you care? No, not at all, What you really want is consistancy, no chops, and more shots per tank. That's what you want. You want the marker to shoot well.

Second, if the above is true, what you really wanted to say is, "My mag is a gas hog, how do I make if more effiecent?"

There are some tricks to an effiecent 'Mag. A good paint to barrel match helps, less porting, and longer non-port section of the barrel.

Also I've noticed that some LX setups have a very slow (almost unaudible) leak, often fixed by going to smaller carrier.

[Sinnet]

When I had some paint that matched it really well (hot spot?) I got 1000 shots out of my classic with a stock RT barrel on it... I dont think the RT valve could be that much worse, you must've had an awful paint/barrel match.

[Brian68mag]

On a lx emag the gun stops firing when around 800psi is left in the tank (for me anyway) So really your 4500 tank acts like a 3700 psi tank. 950 shots off of a 3700 psi system isnt bad....
I suggest you check your gauge before entering a game.
LP=MARKETING HYPE AND MYTH.
Stick your finger in a timmy running at 75 psi, ouch.

The same thing happened to me. Ran out of air. I am only getting 600 shots off of my 68/3k. I am thinking of buying a halo -b and tossing level 10.

umm.. Lower-pressure doesn't necessarily mean efficiency.

In 'cockers, it's my understanding that lower pressure is simply a by-product of efficiency. You get your gun working very efficiently, and then it'll happen to be lower pressure.

if you make it your goal to run as low a pressure as possible, then you're not going to have a super-efficient gun.

besides, a 68/4500 getting 1000 shots isn't bad. And if you weren't "topping-off" your tank after you let the tank cool down, you're not getting 4500 psi to begin with.

[rudy]

well i didnt see anyone say this yet but the truth is with a mag and most dump chamber style guns the lower the pressure the worse the efficiency. centerflag used to make a high pressure mag called the hypermag, they claimed something like 25% better efficiency. I do not know of any dump chamber style markers that are very efficient. there are ways to tweak your efficiency but the mag will probably never achieve what a well tuned cocker/angel/bushmaster can get. and yes with most markers low pressure is a byproduct of efficiency, it also allows you to use more of your tanks air before it drops below the ideal input pressure. on the other hand it is more likely that if you took a cocker that runs great on 200 psi and tuned the springs so it ran at 500 psi you would probably see better efficiency. So really low pressure = less efficiency. which several people here have given good models for in other threads in the past.

[TheBigRaguPB4L]

First off, the rule is the lower the pressure, the higher the volume. That means less efficient. I've noticed people get confused a lot when it comes to effieciency and low pressure. I really believe that LP is really hype. I've seen impulses chop more balls in a day than i have ever with my emag. Of course that impulse was severly messed up, but i've seen it. What i never understood was if it takes higher volume to reach lower pressure, how do impulses and timmy's get such effiency at their reduced pressures?

I've always noticed that the RT's that i shot really consumed a lot of gas. My old school mini-mag did pretty good. I would get about 1500 out of a 68/45. My Rt's would run around 1000-1100. Really that isn't that bad, but i've had better. When i threw my lvl 10 in there, it got kind of worse. This past weekend i got about 800 shots out of a 68/45. Mind you i need to change my carrier and i never got a full fill, but i still was killing the air. It's just been my experience that mags like air, so give it to them.

[omni]

Yikes ... I'm getting about 450ish shots out of my 68/3k on my MicroMag with no Lvl 10. I've got a e-mag comming with level 10 ... so its going to get worse?!

I find when I get down to about 800ishpsi my mag recharges really slow, and rapid firing isn't very good as it sputters.

Mind you when I was testing it out I was using a 13" Armson Stealth with ALOT of porting and rifling that didn't let the ball seel so well against the sides.


What other things besides barrel + paint match would improve my shots per fill?

[Scorch]

I can understand (or think I do) that an older mag may get better shots/fill than an RT or especially an LX Emag. On the RT valve there is more for the air to do. Its not only propelling the ball but applying force for trigger return. Now with the LX there is even more utilization of the air effort.

Why do Cockers get such great gas mileage? (mine gets nearly 1800 shots on a full 68/4500fill shooting 290fps and an input of 240ish cycling the bolt at 40psi) Simple evolution. Each component has gone through several generation of refinement. Spring combinations, valve design, 3 way design, ram design, and super slick bolts all have come a long way from the original WGP design. With so many people working on each part of the puzzle (within a pretty tight frame work), its a sure thing that it will get better.

When I first got my RT, I had a 3k 47ci tank :) Yea.. I spent a lot of time at the fill station. I upgraded to a 91ci which was a beast but I didn't have to worry about running out of air during the game.

I've been flirting with the idea of getting an XMag and running a 45/5k on it. We'll see.

How does having an expansion chamber effect N2? Like when people have a gun thats set up for CO2 and buy a screw in N2 bottle but leave the expansion chamber. Just curious. I'm thinking no one does this for a reason, when they could obviously switch to a reg.

[battlegroup]

Did you really have a true 4500psi fill? Even after the tank cooled down when you left the fill station? How many shots did you put over the chrono? I've seen people put half a hopper over the Chrono/at targets and then complain about running out of air.

[Termite]

Expansion chambers won't hurt but they won't help either. The biggest thing is that thy hold air, if you dump your air between games you are loosing all of the air in the x-chamber also.

That will be a real sweet little gun combo!

I'm thinking about doing that also to persuade my GF to play paintball...

Only trouble is I'm not sure I could bring myself to get it annodised pink

Your guns must be a different configuration than mine. With my old 68 flatline, and hyperframe mag, I got atleast 700 shots on a 3k fill. I even used the shot counter on the Hyper to count it out..

[nuclear zombie]

it's because it's based on a dump chamber design. The air expands to fill the dump chamber which is at atmosphereic pressure after each shot . This repressurizing waste energy and decreases the amount of shots . Where as an autococker uses a poppet valve which acts as an on off, and uses the initial expansion of air to propel the paintball instead of filling a dump chamber .

Low pressure doesn't really mean anything in term of effiency in paintball guns .

The only two ways to get better air effiency is to make a poppet style valve for a mag , which would make it into a blowback ,in other words a tippmann or you could make an e-valve but if your battery goes dead then you don't have the hybrid mode and your dead in the water just like having no air.

So accept that air effiency is the only drawback of the mag , which in all consideration is a heck of a trade-off with all of it's capabilities.
