Edgun Leshiy2 Fill Results?

There is lots of information on a thread here called ( EdGun Leshiy 2). Do some home work there as it will answer all your queastions before you buy and after. Basically the gun is designed to fill to 300 bar. It is a hammerless system so no problem with the 300 bar on the valve. When I had mine set up in .22 I got a little over 3 magazines on a 300 bar fill with my reg set at 130 bar. So that’s around 30 shots. I didn’t shoot it down below the 130 bar. 
 
Got .22 about a month ago. If I fill to 300 bar I get four good 8 shot mags and it seemed to drop off the regulator around shot 36; shot 40 came in 2 inches low at 791fps vs the avg of 837fps. Starting at 300 bar at the end of mag 1 was at 250 bar, end of mag 2 was at 210 bar, end of mag 3 was at 170 bar, end of mag 4 was 140 bar, and end of mag 5 was at 100 bar.

Starting with a 250 bar fill over 24 shots the avg velocity was 836fps with a spread of 13fps and standard deviation of 2.9fps (over the first 16 shots it was 9fps and std 2.4)
