Yeah, that's kind of on the expensive side for my taste - you can get a .50 cal for that. Old M1's & M14's are still popular in some circles, but a little stiff for a lot of shooting for me without a recoil pad - I'm a little guy. The rimmed Russian round is more or less the same as a 30.06, and is still used by them for sniping - about the oldest round still in use, actually. That sounds like a heck of a collector premium there, so unless you're collecting, I'd skip it. You can get a Mosin-Nagant bolt action in that round for about $70 in most gun shows around here these days.
For that money, I'd be getting something new - you can get a full custom sniper grade rifle for that, or if you want it to shoot fast, an AR-10 or SR-25 in the much more common .308 would do fine and have similar if not better performance. Those are better on recoil than a bolt action too, because of the action working in recoil.
(get a copy of John Plasters "the ultimate sniper" and read it - good stuff)
For me, that high power stuff is for real long ranges - or taking out an engine block close in, maybe. In either case, you don't need speed, just accuracy (good optics!).
For closer in, your SKS or AR 15 (preferred by me) is more the ticket. Ask people who've been in combat some - your handgun is just how you fight your way back to the rifle. You use the big stuff to keep them pinned (or wiped out) at longer range, where it gives you a ballistic advantage, just like a long-armed boxer. You can shoot them, but their guns don't reach back.
As they say in the Marines, anytime you find yourself in a fair fight - shoot your planner first, he's supposed to do better than that. That's where the long range capability matters most - if you happen to find yourself in terrain where you can even see 400 yds or more.
I've put lead into my long range benchrest guns in the big calibers to reduce recoil. It really helps as long as you don't have to carry them much. I've drilled out wood stocks and just cast it right on in there, even replaced clips with lead since in BR shooting, the speed of loading isn't that important - and having to load a round at a time isn't all that slow once you get used to it. The extra weight helps to shoot them more accurately, to the point there are now rules about that...weight classes, just like boxing.
Of course, adding your own weight to the gun by properly pulling back into your shoulder hard, pre shot, also helps a lot. Most people don't learn that technique, but it's important on the big stuff or you get bruised. You don't want the gun to have a running start on your shoulder, ever.
