Thread: "Extreme Velocity Spread"!

I can only offer advice on the Chrony that the makers told me when I emailed them for virually the same reasons,speed difference and that was with an established accurate load
I was getting good grouping but large speed variance which seemed weird.
They told me I had my chrony to close to the muzzle and I should move it back to 15-17 feet.

I'd always thought that Chrony recommended 3m, that figure always stuck in my head, however, I just rechecked the instructions and it said "At least 3m from the muzzle of a High Powered Rifle"! Hey, that might not be the problem, however, maybe next time I'll set it out 4m and see if it more consistent!
