extreme cold vs chamber pressure

[parraowneringp]

Just a question it is fact that steel becomes brittle in extreme cold say -35 and below is there a point were it is no longer safe to fire a rifle.Factory loads and somewhat hot hand loads.

Nope. Not under circumstances that you're likely to encounter on this planet.

You're partly right. Quite a few US transport ships sunk during WW2 on the arctic route because of metal brittleness.
Yet I haven't read of any brittle guns during the same war, not even in the -50ºC Russian winter. The only malfunctions seem to have come from frozen gun oil and frozen shooters.
But then again, at -35ºC I'd also be frozen stiff.

I've fired my 22-250 in temps colder than -35 Centigrade...never had a problem, but the coyote did...he he!
