Howdy fellas, My question is this. What are your feelings on hunting rifles that are the most resistant to heat/cold. I know anything with a heavy barrel would be ideal, but I hunt NW Montana (very steep terrain) so packing around a heavy rifle sucks (tried it with my 7wsm and don't want to do it again). My dilema is this, most of my rifles see use from 50 down to -15 degrees, and shoot well at those temps. What I'd like in my next rifle is something useful up here in these conditions, but will also keep it's zero (or at least closer to it) hog hunting in S Texas and Arizona at 100 or so degrees. I found out the hard way that my rem700 in 270win. doesn't like the heat difference at all (and it's not an option to hit the gun range down there). I hate using my Father-in-laws rifles when I'm down there because I'm a southpaw. I should probebly just put a synthetic stock on the 270 and chalk it up to humidity warping the stock a bit or something, but this seems like a good excuse for a new rifle. Also do you think stainless vs blued makes a huge difference. Any in put would be great. Thanx.
