So, is your question more about "Reliability", and "Dependency" of firearm design in adverse field conditions or something else......???
YES , that`s a good way of putting it ? i have never yet hunted Alaska and if i did probably bring a Winchester model 70 with a claw ,no magazine/clip ,30-06 ? i have had Remington 700`s with cold , snow , wet problems it won`t be a 700 action anymore. maybe some of you Alaskan`s have had better luck with some actions that me ?
