You are getting some good advice here.
I have owned several dozen BLRs, or probably more than that. Anyways, I find ALL of the long action BLRs to be "clunky" and, like my buddy two dogs, I would not hunt with any BLR but a short action. My go-to deer rifle for about thirty years has been a BLR 81 in .308 Win - in other words, I got one pretty soon after they came out (in 1981) and never swapped it away. My longest deer kill with it was right around 400 yards, from a prone position at an unmolested and stationary deer. Almost all BLRs will give you 1.5 moa accuracy for THREE SHOTS and some do better. Almost all BLRs heat up and string any shots after a third one, and a typical five shot group is 2.5 to 3.0 moa, still well within hunting accuracy but not benchrest by any stretch of the imagination.
If you want to shoot a magnum rifle, I very strongly suggest a bolt gun.
