Will do mate... I just hope the reg performs as well as the standard but small 'sweetspot'.. Which has proved to be amazing on my 200 delivering groups at 50yards near as good as any PCP out there.

I have 40yards range in my garden I've been pellet testing lately, with its favorite pellets FTT'S at 40 yards I was putting a full mag in a 5 pence size hole (and I'm a average shot at best) that's rested .

Hi ..not as comprehensive as your reports but I was pushed for time and light!

I managed to squeeze an hour of goodish chrono light after work yesterday.. Fill to 190bar*, first handful of shots a tad erratic. 788fps Rising quickly to high 790's.. Then it settled down to very consistant low 790's +-5fps. And there it stayed for 55 shots. Then suddenly dropped to 770's and down indicating low on air (90 bar at refil)..
It's still early days... My freind suggests regs need time to settle... I saw this as the string proceeded I feel, as the next fill had no early fluctuations.

I see you filled to 210bar (hence yeilding more shots) ... Which is a tad more than the *190 AA suggest. Is that because it's regulated now and the pressure at the 200's valve is now well within its working range at a reg'd 90-100bar?

Yes Paddler. Filling an un-regulated rifle to 200 bar (which is what I fill my regulated ones to) would be a waste as it would take ages before you got to the useful part of the power curve. On the other hand, your useful and consistent shots will start from the very first one (or two) after fill even if you have filled to 200 bar.
