I've been playing around with ChairGun looking at various combinations for HFT with my Kral Mega. Using it's "Optimum Zero Range" app gives very different zeros using different kill zone sizes. See images below.What size KZ do you guys use for FT? Do you even use CG to figure out your optimum zero?EDIT: Sorry, I messed up with the CG screen shots with the KZ not being changed. I then tried to modify the images but ended up adding two more. The bottom two are the correct images.
