I've done what I assume most people do when they zero their scopes. I set them all up for a 100 yard zero. Whether it's a muzzle loader for hunting, or one of my 6.5 tactical long range rigs - 100 yard zero is what I consistently do. That got me thinking, why do I do it on my varmint/steel hunting rifles when I really don't shoot anything inside of 300 yards? Is there a reason for prs guys to go with the traditional 100 yard zero? Perhaps am I out of the loop and they are setting their scopes up for a different zero range than that?
 
I am sure that someone more knowledgable will post a more meaningful answer but I do it to avoid any environmental influence on the zero.

At 100 yards, wind, temp, altitude tend not to matter. If zeroing at longer distances (several hundred yards), your atmospheric conditions at that moment need to be recorded. If you move your location and atmospheric conditions change, your ballistic solver can compensate provided you recorded them.

this is more or less my reason i zero at 100

also its just convenient...you can find a 100yds range nearly everywhere...so if you need to confirm a zero, youre not hunting for a place to do it.
