97 cubic foot tank or 4500 air compressor for being a couple hundred miles away from civilization 2000 to 3,000 shots per day thank you

Jokingly I want to say neither. You aren't going to get 3000 shots a day from a heavy great white (i own one) or a compressor. As for the compressor you won't have time for 3000 shots a day and filling.. Bring a dual voltage compressor and a buddy bottle? You may be able to work filling a buddy bottle and shooting to have as little down time as possible.

calculate how much your gun uses per shot. how many shots per fill. how many fills per 96-100cu ft tank. there is your answer.

Compressor= Egg laying hen
Tank- Carton of eggs.

no hen, no eggs. buy a carton sure, but when you're out. You're out. you Could buy a CE rated 98Cu Ft for $260-$320 w whip and valve AND a Yong heng or other twin cylinder compressor for the price of one DOT 96-100 CU Ft Tank/valve/fill whip

example.

Katran L 265cc tube. filled to 250bar nets me about 90 shots to 110bar if i shoot 10.3s at 880-890
a 100CuFt tank filled to 310bar/4500psi will give me 15 fills 110b to 250b.
1350 shots.

Unless you have a LOT of magazines to hold 2000+ rounds you will be spending a lot of time loading magazines.

A 12v compressor is slow. But while you load magazines you can have it top off the gun if it has a large bottle or the 6.8l tank. You might keep up with your air use. You could tether to the tank if the gun has too small a bottle. There are a couple regulated fill valves out there that would allow you to fill the tank to 4500psi and tether to the gun at 2000psi or whatever pressure you want.

Like this

IS this a team effort ? as in your pulling the trigger and a team is loading magazines ? You probably need a few more tanks also , i would say 4 tanks at the minimum with a gas powered compressor For reliable 3k shots a day for ? 2 weeks off grid ?
( not even counting how many 12 volt batteries you wound need to carry for the trip )

Both! Tank and compressor.

Lots of assumptions being made in responses here . . . I think it best to get more info to really answer. Could be a team shooting 10M, or running a range and wanting to provide air, or a serious individual shooter - who knows.

The key is to figure out the average air usage per shot and then you can estimate how much air you will need and go from there. And also the fill level of the guns - if these shots are from a high fill pressure gun then you'll need more HPA. One other key thing is to know if it is OK to finish the day low on air, with refill after shooting / overnight.

Odds are that you are likely going to want multiple tanks and a serious compressor, unless these are low power shots.

So, @Huntvarmint , provide some more info and we can help better.

Unless I've done my math incorrectly, 3000 shots in one day would be 1 shot every 28.8 seconds for 24 hours. For 1 individual. No breaks.

That helps . . . It sounds like you are probably shooting .25 caliber at pretty high power, so you will be using a lot of air. Not as much as big bores, but still using a pretty good amount per shot.

I'll provide a bit of an explanation to help you understand it better. When thinking through "air" for shooting purposes, we have to consider both the volume of the tank, and the pressure of the air. To best do this, I like to use a simplified unit of shooting air that is best called the "bar-cc" of air. This is simply the cc's of air we have multiplied by the pressure in bar. The big tanks are pretty much all 9L of volume (regardless of the stated "cubic feet" of air - that is a whole separate post, but the sticky one on tank volume addresses it), and a full fill is 310 bar (4500 psi). So a full 9L tank holds 2,790,000 bar-cc air - 9,000 cc at 310 bar. It sounds like a lot, but you will be using a lot, and we don't get to use all of it . . . we do not use the air below the bottom of our fill point. If the gun is refilled at 2500 psi (~170 bar), then we can't use the 1,530,000 bar cc below that point - leaving us with just 1,260,000 bar-cc of usable air in the tank.

Then we have to look at the power and efficiency levels of our guns. Most US airgunners talk about efficiency of airguns in the units of FPE / CI, but that unit does not work well with bar-cc units of air - fortunately they are easily converted (1 FPE / CI - 16.38 bar-cc / FPE). Most long barreled high power guns will run around 1.1 FPE / CI, or about 18 bar-cc / FPE, although there is a lot of variability in efficiency in guns. Since it sounds like you will be shooting at around 60 FPE or so, you will be using upwards of 1,100 bar-cc or air per shot.

Put that together, and a 9L tank that is used to refill the gun above will get about 1,150 shots out of a full fill - almost certainly less if not shooting tethered, as there are losses every time we vent the line to disconnect the tank. So unless you are willing to stop shooting while the compressor refills your tank, you will need multiple tanks. The number of tanks depends on whether you are able to refill through the day, and if you are comfortable continuing to shoot while the compressor fills another tank. You didn't say what compressor you have, but at $4500 it is probably up to the task either way. Consider the refill time into your decision, whatever that may be.

You can get 12L tanks that will give you more shots per tank, but they are more than proportionally more expensive (low sales volume) and still won't get you through a day. Personally, I'd prefer to have more lighter, cheaper 9L tanks than maybe one fewer 12L tank and pocket the savings.

In the end, you are going to have to think through what you want to do, but this should help you do that . . .

With a 22 Rimfire and 223 I've shot up to 4,000 rounds in one day I am extremely new to PCP guns not sure on how long a bottle will last I already bought a $4,500 compressor not sure if I would need a 97 or a 100 cubic foot bottle as well I'm looking for information and guidance being that I don't know anything about this I don't want to travel 500 miles and run out of air with real guns I normally take 20,000 rounds I've done as many as 14,000 rounds in a week ground squirrels any help or any information would be greatly appreciated even on your suggestion on pallet weight I was told 25 is good someone else said the 33.9 jsps are better for further range so they'll slap the target harder so it is a clean kill also doing rabbits coyotes that's about it thank you for any information is greatly appreciated

I would think that you are going to want to tether your tank to your gun by way of external regulator. And as long as you have loaded magazines, it will keep you on the trigger longer. Sounds like fun to me! I Iove to shoot for hours on end.

If you can refill at night so you only have to worry about 1 day's air the above suggests 3 tanks for 3,000 shots per day.

Not sure you have time to wait for gun refills to shoot 3,000 rounds per day. But maybe if you have multiple guns and somebody in charge of refilling them. For my guns that are smaller than it sounds like you will be using my GX CS2 fills them in about 3 minutes. Big guns could take 5 minutes. On a 8 amp hour battery I can conservatively get 6 refills. So maybe 4 on a gun storing more air. 50 shots per fill (rough guess) means about 60 refills to get 3000 shots. So maybe 15 8 amp hour batteries. If you have a vehicle with an alternator you could use that to run the smaller GX compressors to reduce or eliminate the need for batteries. Or a small generator would work. I also have two big 120V 15A Milwaukee batteries. They weigh about 50 lbs so they are portable but I wouldn't want to carry them through the woods. They would power a compressor using about 1800 watts. I have run my Yong Heng with all it's peripherals on one. When I loose power I run a critical loads circuit in my house which includes my refrigerator with one of these batteries for 6-8 hours. The GX compressors seem more efficient in their power usage. My guess is you could run a GX 2, 3, or 4 for a day on one of these batteries. But that is just a guess.

I guess 3000 rounds of pb ammo is not weightless either but any way you do it, hauling air to run an airgun at this level will mean hauling some weight. Hand pumps are light and easily portable but a lot of work.

The tank alone by itself would be a horrible investment in your situation. If you are seriously shooting that much you need both. A bigger good compressor that can fill the large bottle. Maybe even a second large bottle.

I have a different suggestion. I have a 100 amp hour 12V battery, lithium ion, for my little fishing boat. It weighs less than 30 lbs. 100 amp hours would be equivalent to about 12 big 8 amp hour tool batteries. So roughly enough for a day's shooting as you describe. The GX CS2 weighs about 20 lbs. So for roughly 50 lbs of "stuff" you could shoot easily thousands of shots. Probably close to 100 gun fills. The trolling motor battery voltage falls as it depletes, however, and I don't know how low they go to get the 100 amp hour rating nor do I know how low you can go and still have the CS2 run fine. Fully charged it puts out 14V which should be OK because it is rated to run on a vehicle power and alternators put out 14V. But it could be that the voltage would drop earlier than I am describing to the point it would affect the CS2. Shouldn't hurt it, just might not keep working well. It would be heavier but they also sell 200 amp hour batteries like this. It still means waiting 3-5 minutes for each gun fill but I sometimes use that time to fill magazines. You could get some idea of how the CS2 reacts to lower battery voltage running it off a 12V battery you have handy. Ideally a deep cycle (like for a trolling motor) but one time depleting a car or lawn mower battery shouldn't kill it. Once you know what voltage will run the CS2 you could look at the voltage curve for the big lithium battery to see how much it would provide.

Thank you very much for the information it is greatly appreciate it when I gave my responsive 2 to 3,000 that is when I did it with a firearm I am very new to PCP rifles do not know their capabilities other than seen over 100 hours on YouTube on what the FX impact sniper can do thank you very much for taking the time to enter the information it is greatly appreciated

Don't believe the FX hype. ALL is not what it seems.

With an fx you better carry as many O-rings as you do air tanks.

If you take transportation weight and space into consideration, .22LR would be the way to go.
