OK ,I live in Alaska!!! I have owned everything from .308 up to my present fav., .45-70 & .458 Win Mag. IMHO leave the .308 at home, it's best for Mule Deer and down. .30-06 is kinda considered minimul up here for general hunting. If you come to Alaska to hunt even remotely dangerous game to include Moose GET USE To MOA and do it with 200-220 grn bullets. Don't shoot your gun in with 150-180 grainers and say you will ajust up to a heavier buller up here. WRONG you are asking for missed shoots or poor at least.
Everything and I mean everything has to be taken to account, weather, humidity, elevation, temp. uphill vs downhill shots. TRUST ME ON THIS!!! If you plan a trip and with you being an out of stater it would be better with a guide. There are unguide hunts just not for Dangerous game. If you go out on the Islands around the state you have to assume the worst case scenario, BROWN BEAR. I was just talking to a friend the otherday that it took 5 rounds from a .375 H&H Mag in the boiler room of a Coastal Brown before it nosed over. This is why shot placement is critical mass. You are standing a chance at being charged in close quarters, adrenaline, fear, excitement, weather conditions, YOUR PHYSICAL CONDITION will take a major role in what goes down or NOT. Don't mean to be negitive or even straying from your original gun talk but believe me all of this needs to taken into acct Bro. If it was me the old Alskan standby is the .338 Win Mag. Ammo is available everywhere cause it is one of the most popular rounds up here. When I'm stompin thru thick undergrowth I go with my .45-70 or .458 They work period!!! If you are hunting more open areas .300 Win Mag (another popular round)-.338 Win Mag is better a choice.
Everyone knows the ABILITY of the .30-06, question is what is your ability. I am not running you down or being negitive towards you in any shape or manner. Just want you to come and enjoy yourself and go home in the same conditon as you showed up. Alive, safe and going home with a grin on your face for a hunt well done. Like I said .30-06 is butt ugly MINIMUM>>>
