As promised I have a few more questions. Any advice in preparing my rifle for extreme cold weather hunt? I am using a 7mag, stainless barrel, and synthetic stock. The gun is only a year old. I plan on degreasing and using a high grade spray oil on the firing pin that I know will stand up in extreme cold. I'm not sure if any other preparation should be done. Anything I should check with the scope rings/mount? Not sure if there are any common failures I should prepare for.

Also, I normally shoot 150gr ballistic tips in Pennsylvania. For our saskatchewan hunt I plan on using 154gr hornady interbonds. Everything I have read is that the interbond will have a controlled expansion that will not separate from the core. The ballistic tips typically have a rapid expansion which work good at the 200 - 300 yrds that are typical in some of my previous hunts. My thought is that given the short range (80 - 130 yds) the more controlled expansion will be better given the velocity at that range. Any advice here?
