Hello, could you help me with the problem I have, it's with a Wilkat MK3 compact, I changed the Huma regulator and adjusted it to 105 bar and the 4 on the adjustment wheel to a speed of 885 fps with a 18 gr JSB, it's a .22 cal. What happens is that if I stop shooting for more than 15 minutes it loses consistency and drops to 865 fps and I have to shoot 3 or 4 times to get it back to 885 fps. I don't know what can be done to stop this from happening, because it's very annoying when hunting. Thank you for your help.
