how good is that?

OK, thanks to Rich for creating and providing the following excel spreadsheets for general use.
He created this spreadsheet so that anyone can input the appropriate data to find out how many fills per scuba tank they'd get from their kit.
How many fills.
The second link gives the user the chance to see, with any given variation, how likely they are to exceed the 12ft lb legal limit.
Am I legal?

Out of interest is there any way of adding guns to the drop down list? I assume they ar ein a look up table somewhere?
EDIT : I've just found them. Although I don't understand how the formulas work to insert an Ultra. It's resovoir is 50cc IIRC

Thanks for that link Pete.
I think I've done it right. I'm just not sure of the empty pressure on an AA S200. So I put 100 bar. Is that right?

Paddy.

If anyone has a rifle not on the dropdown list and they KNOW the reservoir capacity for it, post it on here and I'll add it when I get time.

Pad, 100 bar is not a bad guess. Unregged rifles will be sliding down the power curve at this point. There is no absolute correct refill pressure, it's really when the shots start to drop more than you are prepared to tolerate.
You will get more total shots out of your dive cylinder if you fill when you have to, not keep topping up unnecessarily. Each fill loses the air in the hose and gauge. In the case of the S200 with its small cylinder, the void volume of the hose etc is quite a significant part of the whole. So this is important with S200s in particular.
Thanks for the info.
What I generally do is by going on what I've heard & been told is; fill it up to 190Bar, fire between 40 -45 shots then refill.
I got my 12 lt bottle filled earlier today, so now I can use this as a base & compare. Which means I should get about 1800 shots , not bad when it cost me £2.75 to fill the bottle.

Paddy.

I think it must be down to individual guns and filling systems. I charge my S200 to 180 bar "indicated" on my Hills pump, any more is wasted effort. I then fire a magazine through it and then have 5 magazines more worth of air with very little variation. The pump then seems to kick in again at about 100 bar (so I assume that's where it got to) Mine is .22 and I use AA field running to approx 11.5 ft/lb. This gun seems to hate heavier pellets so I'm hopeful that I'll stay on the right side of the law! I can't say I'm over confident about my pressures but don't seem to be able to push it over the limit.
Cheers Chris.
