I lived in and hunted Alaska 12-years and I started hunting with the 338 win mag in a Ruger 77 tang rifle .I learned quick wood stocks and blued rifles are not the greatest thing In Alaska so I.bought a stainless 338 Ruger 77 mark II rifle .It is super accurate but I was hunting the tundra alot and shots under 300 ,yards were way less than those over 300 yards .I then saw weatherby was making the 338-378 weatherby accunark .I got one then another one and put big 6'5x20 scopes on.them .I also bought a 416 rem mag for the thickets and for a tent gun for bears at night .That combo worked awesome .Now I am thinking about building a 30 inch barrel 338-378 weatherby for even more range .I still use my 338 win mag in.the lower 48 but my 338 win mags in Alaska got loaned to friends who used them up to 300 yards with great success .That's the only down side to the 338win mag but it's an awesome rifle in Alaska but the 338-378 weatherby accumarks made everything alot better.They are like big game varmint rifles .If I can handle them I will try to use the 300 grain bullets in the 338-378 weatherby they add range to then also .
