Hope you good people on here can give me some advice. In the last two GP's my ev2 has been crono'd at 795 at Bolton, near the end of my 50 shots so I crono'd it with my combro when I got home it was running 750-760, but I turned it down a bit on the side port to avoid any danger of going over power. yesterday it ran over the crono at 796. Tonight I've shot 50 shots through my combro with the EV and not registered on shot over 740fps! Using Molly's protarget as a reference, (it was crono'd in both gp's at around 764) tonight using the same crono and the same pellets all the shots registered around 764 give or take 5fps. So, does anyone have any idea how my EV that is running below 740fps over 50 shots can register 795 &796 when measured on the BFTA crono????
