General Question to all of you out there. Has anyone actually counted to see how many more shots you get with a 300 bar bottle vs. the standard 250 bar bottle? I read where people say you will get 50% or 85% more shots, but can't find where someone has actually posted what they went from and to between the two bottles. Interested in what the counts were for 480cc and 300cc bottles.
250 vs. 300 Bar Bottles

This is not exact, but it’s close. This applies to regulated airguns. You need to know how low you allow the pressure to get before you refill, and how many shots that gives you.
For instance, you might get 20 shots when you fill to 250bar and shoot down to 200bar. With an equal size bottle filled to 300bar and shooting down to 200bar, you will get approximately 40 shots. That’s 2x the original shot count. But if you typically shoot down to 100bar, you will only see a 33% increase.
(300-250)/(250-200)=2
That’s 100% more.
(300-100)/(250-100)=1.33
That’s only 33% more.
Be warned that some regulated airguns are not designed to have the regulators fed such a high pressure.

Shooting FX Maverick. So bottle volume doesn't matter based on your formula, correct? So if I get 90 shots going from 250 to 100 bar, than technically I should get 119 with a 300 bar bottle.

You may even open a can of worms when going to a 300 bar fill as you may get more shots, but the shots that are most acurate maybe still be between 250 and 180 bar. My uragan shoots best between 240 and 180 but it is advertised as being a 300 bar fill. With my bench gun I tether so my bottle is always at 200 bar.
What I mean is after going to a 300 bar fill it is possible your first regulator will need to be gone thru or replaced to properly regulate 300 bar

Easy. Fill to 300 bar. Count how many shots to 250 bar. That is how much more shots you get irrespective of what the total count is.

In my experience you don't get as many shots going from 300b to 250b as you do from 250b to 200b

Has anyone bought a carbon tank 18m thread size for Leshiy 2 from Alibaba. I have 2 Leshiy 2'. Bought the carbon tank for 1 of them and was happy with shot count, hate to spend again what I paid for from Edgun west. Sorry if question off topic.

Also, my rifle only fill to 250 bar, but I found, even with the regulator at a fixed setting of 90 bar, that is shoots more consistent and accurate from 200 bar down to 100 bar. So lately I only fill to 200 bar.

I fill to 300 bars on my rated bottle with a reg at 170 bars. If you're running high reg pressure it's a must for shot count.
