Re: Converting yards into clicks ????
IMO, w/regard to speed and precision;
Laser rangefinders have replaced bracket ranging, and ballistic dialing has replaced holding over.
There are many who cling to otherwise for some reason. But add real world hunting situations(not steel target shooting) & someone with a Mk4/NXS scope, Leica Geovid, and a local-recent run click card would truly be better equipped for precision shooting.
I've taken woodchucks with headshots(when that's all I had) beyond 500yds. I'm confident this is not done with FFP mildot scopes, because it's not even possible with them. The reticle would completely obscure the target, Mildot hold-offs are too coarse for the shot, and woodchucks crawl along, and stand, at different heights(they don't play the bracketing game).
