Arrow is 385gr alu, do not think it is interchangeable, but will check. I will up the speed later. At moment shoot just over 200ft/s with regulator at 125bar. Video of 20m shot.
I stay in South Africa and received my Priest a month ago. Got it in 0.22 and 0.25. In both calibres it is awesome. Dropped pheasants out to 55m. In 0.25 I get 47ft/lb with great accuracy. Just Love this gun. Palguns
Nice to get some info on the Huben K1. I am trying my best to land a test unit in South Africa, but just about impossible. Last info from them seems like production problems, maybe fixing some issues. Keep it up, videos will be nice. Paul
