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.

Im not easily impressed normally but I have to admit it, im impressed with the technological knowlege, mathmatical ability, programming skills and general level of intelligence demonstrated by some on this forum.
With a bit of encouragement and if pointed in the right direction I believe that they could actually make something of themselves and be successful in life.
No Seriously. These are useful tools. Thanks guys.
Is there some place to put in the calibre of the pellet

Thank you for the fill chart.. very helpful
Really useful chart. Many thanks.

Careful opening the links if you don't have virus protection. My computer anti virus said they contained malware o steal sensitive information.
Did it say what malware was present in the files?

Being the author can I add a few words of reassurance?
There aren't any malicious things built into any of the spreadsheets that I have put into the public domain. They are purely Excel spreadsheets.
It's the nature of the Internet that stuff gets "borrowed" and placed on other sites. When the first version of How Many Fills was released it was given away in exchange for a promise to donate £2 to breast cancer charity. Lots of members on here did just that. Within a short while the spreadsheet had been hijacked and re-promoted on various US based sites as a free download or to sponsor the site owner. I pointed out that they were basically robbing a cancer charity of donations but it cut no ice. I can't vouch for the integrity of spreadsheets you might download elsewhere, all I can say is when they leave me they are clean.
One or two of my later projects include macros in the spreadsheet, and Excel will often warn you that you are about to open a file containing macros, giving you the option to enable or disable at that time. That's your choice, but the macros are there for the functionality of the sheet, nothing else. If you choose to disable you may find the sheet does not do all that it should.
