Pretty much each rifle has it's own set of rules. I have been lucky enough to own some rifles that didnt have much of a problem down to -10 F. Some others of mine were very unpredictable in 40-50 degree F., others had cold bore shot issues that were more predictable. The best thing to do is get to know each one of your rifles.
Limits are only perceived by what has previously been achieved. Push the limits and good things will happen.
Go the distance or go home
Follow through matters. SEE THE FIRE!!!
