Myself, I haven't yet been able to get one of these fill charts to actually give me a reliable reading yet !
I have a Marauder .22 cal. rifle, a scuba tank rated @ 3000 psi, @ 80 cu. in. ...... I fill it to 2600, every time. Then when the gun gauge gets down to 2000, I re- fill the gun to 2600. Now, when I enter this info. into this latest fill chart it states 4 refills ! BUT the reality is, I now have 14 re-fills at the present AND am still going ( re- filling to 2600). SO, as you see, I am having a hard time getting actual reliable info. with fill charts. .... Any ideas / opinions ?

Scuba tanks are rated in cubic FEET. In your post you noted 80 cubic INCHES.

Use 677 cubic inches for an 80CF SCUBA cylinder. I answered this question in more detail in this thread: http://www.gatewaytoairguns.org/GTA/index.php?topic=42828.0 (http://www.gatewaytoairguns.org/GTA/index.php?topic=42828.0)

I usually use this PCP refill calculator - http://www.calc.sikes.us/2/index.php (http://www.calc.sikes.us/2/index.php)
For the MRod .22 -> Enter 215 in the field "CC of your gun's tank"
For the Condor .25 -> Enter 490 in the field "CC of your gun's tank"
