While its a great round I would not call it a beast compaired to others. I have one and really like it. Very accurate and easy to shoot well. I recently had trouble with a dura sight base. I put a EGW on it and its great now. Any good ring should be fine. Stay away from the cheapo ones. Scope you mentioned should be fine. As for ammo. I load my own but the 140 corlocks I bought for brass shot well for me. Now 120 NBT is all ill use

The Burris you suggest would be great. I have one on my .300 Savage XP-100. Get it with the Ballistic Plex....though you may not see a need for the BP now, it won't get in your way and you may find it useful later!

Weaver bases have always treated me well. Mount the scope in Burris Signature Zee rings (medium height). That's the same set up I use on my long range XP's and it's never failed.

Grip and forearm....get Pachmyers and be done with it!

Some here have had trouble with the rifle forearm ,breaking or pulling screws thru the wood.For the forearm lighter is better
as it dosen't have the tendancy to break or pull screws. A friend has one in 350 rem.mag and has broken two sets of screws.Suggested he put the ryonite forend back on, and it stopped the problem.

I have big forearms on all of my TC's. 375 H&H AI, 35-06 JDJ, 8mm GNR, 270 Win, and all but the 375 H&H AI have hanger bars. I have run hundreds of rounds threw my H&H and I havent had any problems... With a 7mm-08 you can put anything you want on it.

I have to agree 98.9867452301% with Dan. I just like the high rings. I dont have any problems sticking my thumb between the scope and hammer. In a handgun and shooting under 400 yards, I dont think you will ever tell a differance.
