Hello everyone, good morning. I have a few questions. Yesterday I was shooting my .22 caliber FX M4 sniper rifle, with the 1:16 scale heavy-duty liner and carbon fiber overlay, among other things. I shot 34-gram bullets, which worries me a bit, since I set the throttle to 160 bar and only achieved 940 fps. My question is: Is 160 bar fine at that velocity with the macro at 16 and the minimacro at 5, or is there something wrong with the throttle? I would appreciate your comments, friends, and your kind help.
