100 cubic foot 4500 air tank or a 4500 air compressor better for being a couple hundred miles away from civilization for a week 2 to 3,000 shots per day
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.

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 )

I hope you’re good at replacing o-rings too!
But seriously, have you ever shot that many shots in a single day. Sounds a bit unreasonable to me.

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.

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

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 unit of 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 or guns. Most US airgunners people 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 barr-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 proportionally more expensive 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 . . .

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.
