I carry a 264 Win Mag that shoots great and can reach, but weighs 10.5lbs ready to hunt for antelope and whitetail, some plains muley hunts. For a mountain rifle I saved up and had Rifles Inc build me a 300 win mag in a modified version of their lightweight 70. I could have saved a considerable amount of weight, probably 3/4 of a pound, by going to a Remington action. I've been using Winchesters with their 3 position safety for so long I chose not to, I like my M70 actions. I also went with a 23.5" #3 fluted barrel instead of the lighter barrel they usually use on the lightweight 70. The rifle ended up at 7 lbs 4 oz with a Swaro Z5 3-18x44 and sling. It does have their brake on it. If you buy the rifle and scope from them they will find a load and send 2 turrets for different elevations with the completed package. I usually do my own load work, just finished building a load for a 25-06, but I figured this time I'd save my money and let them do it. The load they came up with is a good one and the turret is spot on from the practice shooting I did once I received the gun.
It's about perfect in my opinion and should be for the cost. I'm shooting 180gr Accubonds at 2956fps and can hit the 10" gong at 500yds very reliably. I took my muley this fall at 358yds and it worked perfectly. I like this weight, it's not to whippy when quickly targeting a running buck up close but not to heavy to pack. I could have certainly built a lighter rifle but this fits me and the recoil is very manageable. I developed a flinch years ago and while I have it fixed now I am careful not to give it a reason to return. I really considered going with a 7 mag or 264WM but I have a moose hunt coming up and decided to go with a bigger gun. It's more than needed for muleys, about right for elk, and enough for moose. If I'd have went with a lighter weight gun I'd likely have gone with a lower recoiling chambering also.
