Advice which gas bottle

[jetski]

i have 3 pcp's that i fill to 170 bar each(below what the manufacturers state)
i have a 12l 300 bar bottle,i have done 78 fills on my guns which i fill to 170 bar,i top them up when they get down to around 100 bar
have just done a pressure test on my bottle and still have 200 bar left
the calculator is there as a guide as to how many fills you may get not what you will get
if you get less its not my fault
its not my website

Your data doesn't have a conclusion, so I have no idea of your point.... My s510 gets about 20 fills from my 300bar 3 litre bottle. Full=190. Empty=125.
And I wasn't blaming you for the inacurate calculator, just asking you if you found the results matching your own findings as mine are very different. There's a big difference from 20 to 33. If it was out by about 5 fair enough, but it's out by well over 50% so I wanted someone else to put it to the test also because if it's that much out every time it's pointless...

point of order gents,they are not bottles but cylinders.please dont put gas in only breathing air.i only say this because i am trained in the use of cylinders,beer comes in bottles

some people say diving cylinders, some say diving bottles, some say diving tanks, they all the same thing and either term is completely acceptable
