I am looking at getting a new rifle. I am going to purchase a new barrel for my Thompson Center Encore. Right now I shoot a Remington .270 which was awesome for deer hunting in NC but now I am living in Alaska for the next 3 years and need something a little bigger. I am not one of these people that feel I need to own the biggest gun made by man, I just want an adequate gun for taking moose, Kodiak grizzly bear and most of all, Dall Sheep. Now, what I am looking for is a gun that can knock down a brick wall at 200-300 yds for the Bears, and a gun that still has knock down power at 400-500 yds for Dall sheep. I was looking at the 7mm but did not know if that was the best. Also, was a little confused because I see a couple different 7mm. (7mm, 7mm-08, 7 mag) Thank you very much for your help. You guys are a great resource. Jimmy

Why not a 338WM? Oughta work great on the larger stuff, and the 270 is still there.

There is a 300 win mag barrel for sale on the classified forum.

7mm is .284" and is the diameter of the bullet. In OK, when people say 7mm, they are usually referring to a 7mm rem mag.
Other 7mm's include 7-08, 7x57, 280, 284 win. 7wsm.

I probably agree about the 338 wm if alaska bears are included. I'm sure a 300 wm is alright if you have another hunter with you with as a backup.
