Hello from Colorado. I'm a new member of the Alaska Shooting forum and would like to introduce you to a wonderful 338 Win Mag load I've used successfully for years. My son and I have used it extensively on elk and deer here in Colorado and on Black Wildebeest, Oryx, Kudu, Wart Hog and numerous smaller plains game in Africa. The African animals are really tough. All of our Africa kills were one shot kills that put the animals down instantly!
It was much the same with elk here in Colorado.
The 338 load originally came from Bob Hagel's book entitled "Guns, Loads and Hunting Tips" 1986. His published load is 77 grains of IMR 4350 behind a Nosler 210 gr. Partition bullet. That load chronographs out of my Rem. 700 and my son's Model 70 (24 and 23" barrels) at 3125 fps which calculate to 4555 ft lbs of energy. In order to get that much powder into the case you need to use about an 18" drop tube and the load is compressed. We have used the load since 1987...Great load! The load is very accurate. I shot my last elk this fall at 425 yards...killed it dead.
The 338 case if perfect for this load..when you move up to the 250 gr. bullets there just isn't enough space in the case for enough powder to really make this as efficient as the 210 load. You can get 2750-2800 fps but thats about it. If you want a really good 250 load you need to go to the 340 Weatherby or the 338 Ultra Mag...both long action, long barreled rifles. The 210 partition is one tough bullet with lots of penetration capability.
I think this would make a wonderful Alaska load for any thing you may want to hunt..a great sheep load where big bears roam and may be encountered...any where in AK... do bears crap in the woods. It's very accurate and I would shoot at ranges of 400+ without hesitation. This would be my choice for an all around gun anywhere, except Cape buffalo and such.
I have really enjoyed the shooting forum and hope to contribute...enjoy and have a wonderful Christmas....don't forget the reason for the season!
