A guy I knew who worked in Alaska was issued a 375 H&H Magnum (300 grain bullet at 2600 fps). He had to qualify by shooting it from the hip. He considered it a little small for his taste.
I was a forest ranger at the Kenai Lake Work Center in Moose Pass, Alaska many years ago, and that’s what we were issued: .375 H&H rifles.
They were pre’64’s, which are worth a lot of money, but when I told the camp director that we should sell them, buy modern Rugets for a fraction of the price, and use the profits to upgrade our snow machines and stuff, he told me the government didn’t work that way!
I really enjoyed my years up there on the Kenai!
