Most deer are shot at about 100m or less. It therefore makes sense to zero at 100m and aim off for anything different, otherwise you are shooting the majority of your deer with a rifle that is effectively not zeroed!

I zero 1 inch high at 100 yards ,
a friend of mine thinks 200 yards zero is more popular and a better range to zero at.! We will see on here.
I don't agree. I've shot to have a Point of Impact of 1 inch high at a 100 yds since the late '60's. That was long before I'd ever heard of maximum point blank range and it's served me very well ever since. I don't record the ranges I shoot deer at, but working back over the last week, it's been 140 yds, 46 yds and 190 yds at roe buck.
I didn't give any consideration to holding off for any of these roe buck.

It's hard to find locations to shoot at 200yds and not have the wind impacting on the group. When it's very windy, I will check zero at 50 yds and I expect to be dead on. From time to time I check zero at 100 yds and I expect to be 1 inch high. More rarely I check for group at 170 yds and I expect to be dead on with a group that is influenced by whatever wind there is.
What is important is to have the same set-up with every rifle that you shoot so that the sight picture is consistent. Shooting well is about doing a few simple things consistently.

Bang on at both 50 & 170 and only an inch high at 100m? Really? What are you shooting as that seems to be incredibly flat?
Even my .280AI drops about 4.5 inches from 100m out to 200m. I try to treat every deer as an individual target and adjust each sight picture according to its range. Much less room for error that way. Dropping several inches on a roe out at 200m without aiming slightly high is just asking for a wounded brisket shot. Knowing the trajectory of your rifle at various ranges is essential and allows you to place the shot exactly where you want it. What you choose as a datum point, whether it be bang on or high at a chosen range is personal preference, but if you want accuracy, then you need to adjust. There is not much room for any human error if you are already several inches off due to effective zero error!
