I've shot R17, H4350 and H4831sc in temps ranging from below zero up to about 90F.
Didn't use a Chrony everytime but shot out to 400 or more yards as I'm more interested in POI shift rather than actual velocity loss.

For hunting purposes out to 400 yards in temps ranging from 10-90F I wouldn't worry as I didn't see much if any difference in POI. When temps did get colder than 10F accuracy went to hell in a couple rifles.
