Looking at buying a taipan vet long in 25 cal. More than likely I will buy from Talon Tunes. I seen you can adjust the fps with just the hammer spring. Looking to get the jsb 34 grains at 895 to 905. Which Tony told me he could do. But my main question is does anyone have this setup and how many shot do yo I get on a fill. I was told by a member he get 4 mags or 40 shots.
