RE: Elk Gun For Wy. High Country
If it were me it would be either of the Sako's. My reasoning would be ammunition availability, cost of brass, amount of powder required, recoil, etc. The .338 would be great with 250 gr accubonds or comparable for those quartering away shots but in almost all shots the 300 Win Mag would be a great choice as well with . Quartering away and through the rib cage and into the lungs.
Which caliber will you be the most comfortable shooting, and which cartridge will give you the most confidence on your hunt?
I am doing a moose hunt in the Yukon this fall and I am shooting a new 7mm wildcat I developed. My back up gun will be a .338 Win Mag.
You aren't going to be shooting this guy probably even at 300 yards let alone 4 or 500. Hit right at reasonable distances any of these guns will drop Mr. Moose where he stands.
Good luck.
