even a trip to alaska one day
Once you put in those magic words, it is a whole new ball game. The all round rifle just does not exist, if you include Alaskan Brown bears. Jack O,Connor would say: well, you need your light weight .270 for the mountains, your long barrel .270 with bi-pod for the plains, etc.
How about two since you have $1000 to spend? The .270 I won in a raffle is a Remington with scope. They sell for ~$350 online. That leaves $650 for a .338 Mag that you will need in Alaska. However, people do trade guns.
Buy a good one now under .30 cal, and trade later for bigger, if and when needed. Any of the 7mm/08 or .260s or the new Super Short Magnums (SSM) will be hot sellers for a while and will make a good trading gun later.
Any caliber like the .300 Win Mag is a has been for trading and I see them
~$50 less than the new .300 SSM, so avoid the wonderful old calibers like
.257 Roberts , as the new SSM are what's hot now.
