im having really bad 1st shot velocity spike with my mag. the first shot is always somewere inbetween 350-400 and drops down to 250 after the first shot. It will stay right around 250 as long as i keep shooting, but after it has a minute or two where it doesnt shoot its back shooting upwards of 400 again. my setup is rt pro with x-valve, level 10, ule trigger,and a ACI bulldog tank. thanks for the help
