@Rakemaan . Thanks for the comments. I looked at some of your videos and you work with quite a variety of equipment. Estimating the start and stop pressures on your 185 cc gun, that really is an efficient shooter. Efficiency is such an elusive target. This gun doesn't have a hammer, it uses an air operated valve that I built. Getting it to close repeatably was the trick.
@1227air500 These are excellent results for both power level and air efficiency, I have only got better efficiency at lower power (e.g 3090 fpe total from 185cc) with 28" barrel. Your electronic system must eliminate valve bounce and have rapid actuation.
KingLoopie1, Glad you enjoyed the video! Yes, definitely have enough pressure left for a few more high power shots, even when I'm using the .510 cal barrel. I haven't tried a shot string with the .510, but with the .458 barrel, I got 7 shots of 500fpe each. So that makes about 3,500 useable FPE from one fill of the 380cc tank. A little scary when its throwing 405 and 575 grain bullets.
Amazing! What's next? 110 cal? I think you could probably kill most anything on the North American continent with this one (maybe big bears excepted). Any pressure remaining for a follow up shot or 2?

The video is too long in the middle. After the shooting part, skip to the end.
