I am a clicker, so i only use the Christmas tree reticle when changing distance and gauge how APPROX clicks i have to adjust mainly elevation but with a increase also often sideways adjustment have to be made.
Some times i get it bang on with just 1 shot, but i will at times need 2-3 shots to accommodate increased sideways wind load.
Or that is used to, CUZ i have now changed distance so often that i know going from 55 M to 118 M i have to adjust so many clicks
It is extremely rare i use hold over / under to shoot in general.
Which remind me.
Shooting paintballs at 100 M yesterday with the usual 13 gr Zan. a dove landed in a treetop way behind my friends property, so i changed to 119 M adjusted for that and did 1 shot that was 5 clicks low, i then added 30 more clicks CUZ that bird was far away.
Took a shot at it and i removed a few feathers from its tail and it then flew away.
I would have hit it if i had remembered to hold for the additional longer from the left wind exposure, i am sure 1/2 MIL or 5 clicks i think would have done the trick CUZ not much wind.
Then picked up range finder, and to my astonishment that tree top was at 202 Meters or 220 yards, shooting up at a 15-20 deg angle.
