I would not hesitate using my doubles in any climate and on any game. If I new it was going to be very very cold I'd have the gun de-greased beforehand. Amy buddy of mine who trains in artic conditions says grease can become so viscous as to dramatically affect the strikers and possibly case a misfire.

A word on gun worship (or any object for that matter). The average remington owner often has said to me "I'd never carry that fine gun into the woods" I say "Why not"!? The gun maker made the DR beautiful to behold with lovely wood and fine metal work, but by god he made it to be used! If my gun gets scratched up, the wood gouged, or the bluing worn - fine. Those are marks of use the maker would be proud of. Especially if the in the course of use, it brought home the meat.
