Re: Sendero or 112 BVSS ?
I don't know how experienced you are in LR hunting, so I can't give you any voice of experience as I'm new myself, but I can tell you what the crowd in here likes.
The guys here really like the 300 Win. Mag as a long range caliber. It's got a long history, many followers, and tons of reloading data.
Personally, I preferred to get a 7mm Remington Ultra Mag in the Remington 700 Sendero Stainless Fluted. For me, it is about as close to custom as I can afford. It's a really flat shooting cartridge and is plenty for shooting whitetails out to 1000 yards (if I can [img]images/icons/wink.gif[/img]) I recently got it, haven't shot it. I'm topping it with a good scope, adding a bipod and will be shooting handloads.
I don't think you could go wrong with the Remmy or the Savage (Savage has come a long way) - both have been reputed to be good factory production rifles. If you're working on a tight budget though, I'd get the Savage and spend the extra money on a GREAT scope (target turrets, fairly high magnification, parallax adjustment OR adjustable objective) and either a bi-pod or "The Ultimate TriPod" some of the guys in here use. Don't forget about components for reloading (if you do reload, and if not consider getting into it, custom or match grade bullets are often used in LR hunting). Most all the shooters in here reload because of the accuracy required.
Hope this helps and good luck!
