well, I hunt about 80% of the time with a synthetic stock/stainless weatherby MARKV in 340 wby caliber and Im forced to say Ive never been to alaska but I do backpack hunt for days at a time in colorado, and wy on occasion for ELK and I see lots of snow and colder temps on most hunts, now I don,t SPRAY down my rifles, but I do disassemble them from the stock and wipe them clean and clean them carefully almost every night, and Ive never had return to zero problems (but then Im happy with consistant 1"-1.3" groups in an elk rifle)
both rifles are heavy but the a-bolts almost a full pound heavier, and a 375H&H has no advantage Ive seen on ELK over the 340wby
