AGT Vixen Long .22, Shot count at 200 bar question

[fusion]

Hello. I am interested in the AGT Vixen Long in .22. I see the shot count at about 60 on the regulator when filled to 300 bar.

I have a YH compressor that I use to fill my bottle to 4200 PSI. I don't want to push my compressor any higher than that. So, that kinda limits my fills on air rifles to about 200 bar.

All that being said, how many shots can I expect on the regulator, when filled to 200 bar?

Thanks!
Mike
