Talk me off of the "Darkside" ledge....

Will a 3000 psi tank fill a 3000psi airgun?  Do you fill the airgun to full capacity?  How many fills on 3000 vs.  4500?  I can get a used 3000 psi tank at local dive shop for $60.

The friend who has my M-Rod has an older STEEL Scuba tank and the local shop will overfill it to 3300-3400 psi and that allows him to fill his M-rod something like 18-20 times to 3000 psi then when it wont fill all the way he tops off with his Hill pump. But not all dive shops will do that and he claims its only with the steel tanks.

You need a tank that can be filled past 3000 psi to re-fill a 3000psi PCP. That rule I do know. A 3000 psi tank will fill it, just not to 3000 psi.

I have a 90 ci guppy tank and can fill my rifles from 100 bar to 200 bar about 12 times

Is a guppy 3000 or 4500psi?

Cool. Thanks.

The ideal setup is 4500 psi. With a 88 cu ft tank you will get a little over 65 fills from 180 to 300 bar. Say 35 shots per fill is 2275 shots per tank.

A 80 cu ft 3000 psi tank will start falling off each fill. So after the first fill to 3000 psi on your PCP the second would be 2970, then 2940 and so on(numbers used as examples). As BZ stated probably 12 - 18 fills. If you had a pump and a 80 cu ft 3000 psi tank pumping would be a lot easier. Most guys that pump only pump to 250 or 270 bar. Because the last few hundred psi are the hardest, plus most PCP's are more efficient with lower fills.

If you are pumping or the nearest fill is far from you. Or just expensive look into a regulated rifle. Two nice regulated PCP'c in the same price range as the AA 510 that come to mind. Both will get almost twice as many shots on the same amount of air as the AA 510.

I have a "minnow" size 90CI tank vs the Guppy being about 110CI.  Both are 4500 psi.  They are I freeken deal for going out and about if, and probably only if, you bite the bullet on a shoebox setup.  Otherwise one large tank is the way to go due to the cost of fills as well as time and commuting to do so. 

I started with an 88 footer but only will take that with me if I'm going out of range for a week or so.  Maybe not even then, I'll just take a springer along (as if I'd be caught dead without one, anyway).

Bigger calibers take more air.

Best and I mean best group with a springer was .34" at 40Y (.177 R11).  That's about as good as I can do with a PCP at 50Y (actually .242" at 50Y [HM1000 .22]) which means translated to about 1-1.5" at 100.  1" cherry picked, 1.25-2.5, not.

I've never tried the springers that far, yet.  I think they're all fun, but not necessarily night and day as some would have you believe.  Now if you need to hunt at 50 or 75Y, then I'd change my tune for what knockdown power is available along with the accuracy of a larger pellet.

Guppy tank and Freedom 8 compressor is a good setup although there are a couple nice all in 1 hpa compressors starting at ~$1,400 and up to $1,800  Dave / D Ez just posted about 1

Although not exactly quick, nothing wrong with my chain driven shoebox.  I wouldn't have had to change the seals had I done a leak test on my fittings
