I am contemplating on purchasing one of those PCP air rifles, got my eye on a XS-B50.

My main concern is how many shots can one do with one of those rifles. I see tons of people talking about them, the power they deliver etc, but none state such info.

I know someone with a B50.... I'll ask him....

From memory he said about 25 shots starting at 2600 psi down to about 1500 psi.... that was the sweet spot for a stock gun.... He's going to check his notes tomorrow and if this information is incorrect I'll update it....

I do remember him telling me that on a stock gun 3000 psi was too much, the valve was starting to lock up.... That's not all bad news, however.... It means you can get quite a few fills from a 3000 psi SCUBA tank.... Mr. Green

I saw an extensive "how-to", with lots of pix, about installing an andruis rgeulator in on eof those B50's...from what I remember, it significantly increased the usable shot count..might be something to keep in mind, if you DO get a B50...might be something you'd want to do later on....

Bear in mind that any regulator installed directly in front of the valve will work better when set for slightly reduced performance (ie a lower pressure).... They get the increased shot count from a slight decrease in power but enable the gun to be filled to the 3000 psi design limit without the valve going into lock....

For instance, it would be typical for a regulator for a gun such as the B50 to be set at between 100 and 120 Bar (1450-1750 psi).... and the velocity similar (or a bit less) to what you would get at that air pressure....
