That would be if you're a dial twidler would it not? Personally, not being one of the former, I've always sighted in at 200m and never had any problems out to 300m with a 7mm/08 and .308 which is about as far as I'm prepared to shoot, with the odd exception. I'd do the same with a .270 if I owned one.

I suppose it depends on the country you're usually hunting in and what cartridge you're using.

If a bush hunter or shooting 0-200m biggest percentage of time sighting in at 100m is perfered. Dial up or using ballisictic plex 100m is perfered also.

I agree if your shots are going to be 150m or less, preferably even 100m or less like most bush hunters would encounter.

The draw back to using a 100m zero though is that if you see the odd deer at say 300m there is about a 38cm drop. With a 200m zero it's around 5cm high at a 100m and that's not going to cause any misses. At 300m there is a 20cm drop which just means a hold on the spine or just below.

Using some common cartridges zeroed in yards.

260 Rem - 140gr

100 Yards +2.7”
150 Yards +2.9”
200 Yards +1.7”
250 Yards +1.0”
300 Yards ‐5.5”

.270 Win - 130gr

100 Yards +2.6”
150 Yards +3.0”
200 Yards +2.0”
250 Yards Zero
300 Yards ‐3.75”

7mm/08 Rem - 140gr

100 Yards +2.7”
150 Yards +3.0”
200 Yards +1.9”
250 Yards +0.6”
300 Yards ‐4.8”

308 Win - 150gr

100 Yards +2.7”
150 Yards +2.9”
200 Yards +1.7”
250 Yards ‐1.2”
300 Yards ‐5.8”

Yes for dial up. Each to their own but I personally don't have much faith in ballistic plex reticles for judging distance. Animals come in different sizes.
