air effeciency with x-valve

[kwood]

iv been trying to read through the posts and find out the answer to my question, but have had no luck yet
i simply wondering how efficient the x-valve is with a 68/4500 (crossfire 850psi preset)?
how many shots would i be able to get out of that tank with a properly tuned xvalve w/ ult, lvl 10?
and next would there be a large difference with a pneumag set up since air is being used to operate the trigger as well?
if this question has already been posted and answered, i apologize in advance, but i have tried looking around
let me know what your experiences have been

with a 68 4500 expect 1000 good shots. Pneumag will see the same. Pneumags air useage is really not noticable over a regular triggered automag. Thats the only real issue with automags is efficency. I would get a 90ci 4500 tank, 1500 shots of it. is what I see.

Efficency with a automag also has alot to do with the way you tune/if you use the Lvl X. You would see slightly better air useage with the standard lvl 7 bolt, but you will end up wasting that much air shooting all the broken and choped balls out of your barrel.

Automags are high pressure guns, the air useage issue has alot to do with their ability not to shoot deep into a tank.

Most of the time my automags cant shoot below my tank reg pressue. Crossfire 850psi output tank, the mag will likely not be able to function correctly when the tank gets below 850psi.

So getting that 68ci tank "hot" filled to 4000psi minus the 850psi is like really having a 3250 psi tank of useable air.

My mags set up on adjustible 1200psi tanks loose their RT effect and function quickly once below the tanks output pressure.

Unlike my MacDev droid with an LP tank....I can shot it almost bone empty with no noticable shoot down...thanks to the droids 100psi operating presure.

I love my mags...just wish they were not such air hogs.

I can get 1500 shots from a 68-4500 on my emag setup using the middle spring in my level 10.

Im probably in this area also. I think ive figured around 1300ish, but only guestimates.
