Atmospheric Conditions from Zeroing Your Rifle with Bryan litz

That sounds great, unless you shoot farther then your zero range? Maybe I completely missed the intent of that video?
 
I get that atmosphere is not going to affect your 100 yard zero, or your 100 yard shot, but wouldn't a large temp swing change that at distance? For instance zero at 40*, and shooting somewhere warmer at 90*?

Not enough to matter.
As an example using JBM's default environmental settings and a Sierra .308 168gr MatchKing at 2400 fps:

Same projectile at 109 ' F and 1 fps per degree increase (2450 fps)

It isn't even 1 click on most scopes.
