I am specifically referring the above question regarding those who are considering purchasing an Air Venturi Avenger. If a prospective buyer is thinking of hunting something the size of a groundhog (aka woodchuck) out to 100 yards or better, then having the rifle tuned for heavier pellets or slugs is what they would want. My question is, which filling option would be best for getting as many power tunes as possible? Can the large scba 4,500 psi tank give multiple "power" tunes, or would the ability to fill to 4,500 psi be quickly diminished after the first couple of fills? Or, since the regulator and hammer spring are set for power, is it only a case of getting fewer full power shots with each fill before going off the regulator? I really would like to fill with a scba tank, rather than get into having to use the more expensive and involved compressors available. Of course, one fill from the tank would give more shots than would likely be afforded while hunting. So, I wouldn't necessarily need to go back to my vehicle and hook up the compressor to the battery. Returning to the vehicle and filling from a tank would be must quicker, quieter, and easier. I am just trying to get a handle on what it really means to have a rifle that can be charged to 4,350 psi. Is it really better to have a rifle that takes, say, a 250 bar fill? Would such a rifle afford more "power" fills from the type of tank I have mentioned? Thank you for your advice in clearing my thinking regarding the implications of filling a 300 bar rifle from a tank.
Is a compressor a better filling option than a large 4,500 psi carbon fiber tank

Usually the higher the fill pressure, the harder the hammer spring has to be set in order to open the valve which coincides with your high power tune. If you have a place that will fill your SCBA to 4500psi then like you said it is a quicker and easier way to fill your PCP. If you have no way to fill the SCBA then a compressor is the way to go....then get a SCBA down the road that you can fill with your compressor. Depending on the SCBA’s volume, is what determines how many fills you will get and far you shoot your gun down to, I myself don’t shoot till I’m off the regulator. Once you have it tuned you will know how many shots you’ll get before going off the regulator.

If you took your tank to a dive shop or a fire department where they would fill your tank to 4500 psi or 310 BAR ... then you would MAYBE get 2 complete fills for your Avenger if you are bound and determined to fill the air reservoir on your gun to the maximum ... assuming that you can get the dive shop or the FD to fill your tank to 4500 psi ... most leave themselves a margin of error and only fill to about 4200 psi.
I very rarely fill my guns that high because that much pressure wreaks havoc on your o-rings. I have a Cricket that I can fill to 300 BAR but seldom go past 250 BAR and then shoot down to where the gun goes off the regulator before filling again.

The ability of a tank to fill a gun or smaller tank is most definitely limited to the pressure and size of the supply tank. A large 4500psi tank filled to 4500psi should fill the tiny tank of the gun several times to 4350psi. But even after that it will fill it many more times at a slightly lower pressure. The gun does not need to be filled to it's max pressure all of the time and some guns shoot better at a slightly lower than full fill. A large tank should let you shoot all day like over a thousand shots if you so desire it.
But finding a place that will fill your supply tank to 4500psi can be problematic. In my area most shops only will fill to a bit over 3000psi.
My Great White filled to 4200psi with my Yong Heng fills my 580cc Impact tank to 250bar five or six times and then to slightly less another five or six times. So I can shoot the Impact all day then retire it and shoot my guns that fill to 3K for quite some time as well.
It's best to have a tank and a compressor. I bought my tank first then a compressor then a larger tank. Now I can shoot as long as I want and the addiction can never complain that I ran out of air.

I don’t believe you’ll get a full 4500 psi fill for your SCBA, especially after the SCBAs cool off. You could settle for a tune with less shots and not fill your PCP to the max. 20-30 shots is more than enough for hunting.

I guess I don't exactly understand the question/issue.
My wife has a .22 Avenger. It's regulator is set at 1900psi +/-. If the rifle is filled above that, it shoots at that. Period. The regulator can only be turned up to 3000psi max.. so again, everything above that is "shot count".
We did a 40 shot string the other day, started at about 4100psi. her velocity was 970 +/- 7 fps for the whole string. She was still on the regulator when she finished.
The higher you set the regulator, the fewer shots you will have on it, regardless of the fill pressure. If you think every fill HAS to be to 4350, then a compressor is possibly for you. I have not tested it, and probably won't ever, but I would guess we would get a couple 4350psi fills from our tiger shark, if we only filled that one rifle. But we don't. We happen to live not to far from a very good paintball place, we get a real 4500psi when we fill, they give the tank time to cool, and top off, twice. Best $5 I have found to spend on the hobby.. LOL

Pcpwannabe the first question is do you have a reliable shop that can fill a tank to 4500psi? How close is it to your house and how expensive is it? You don't want to go back multiple times a day or week to shoot and tune your gun. Having your own compressor is life changing when you shoot a pcp. I hand pumped for years and it sucks but that's all I could get. At first I bought the tiny 90cubic inch 4500 psi tank and got the air ventury compressor. Then wish I had bought the bigger AV Tank which I eventually did. Life changing. I used to shoot a lot. If you can't afford the big compressor and the big tank I would just get the one you were talking about and save up for the bigger more expensive stuff over time. If my compressor ever fails I will probably just sell my pcp rifles and go back to my springers due to not being able to shoot much anymore. Good luck with whatever you choose.

I use an Air Venturi compressor to fill my 44 and 88 cu/ft tanks. I like this setup the best, for my situation. The tanks are portable and last a good while, and the gun refills are fast from the tanks.
I use to get $5 fill-ups from a scuba shop until they changed the rules overnight on tank refills. I have a lot more freedom with the compressor now, and it hasn't given me any trouble in several years with 4 guns, two of which are big bores.
