Well, deuce; the reg gauge shows 150 bar. I want to run a complete shot string to get a better idea of what's going on. My tank is reading below 250 bar, yet it is having no problem filling my bottle to its 250 bar mark. It just keeps getting curiouser and curiouser! Also, my Chrony may be off too! Who the heck knows?! I ran my first string right after I got my Impact. I want to see how it settled-out now that I've shot a whole tin through it. I'll keep you posted! I guess the bottom line is if the bunnies drop at 100 yards, I'm good to go, right?

! All readings are from the factory gauges with no tweaking. I used a Master Chrony. My reg is set at 150 bar. I shot 44.75 gr JSB Diabolo Domeds. I started with a bottle pressure of 250 bar and shot down until the reg pressure started to drop. I got 37 regulated shots with an average of 877.8 fps (76.55 ft-lbf). The reg pressure started to drop after the 40th shot (@ 864.6 fps) when the bottle pressure read 155 bar. The SD and spread was a little high at 3.74 and 14.5 fps, respectively. But, there was one outlier at 869.9 fps which skewed the result somewhat. So, for all intents and purposes, the performance is as advertised; and the gauges are accurate, given that they are analog and are graduated in 50 bar increments.
