Spinafish: If you want a scout type rifle in a 6.5 caliber, get yourself a Model 38 Swedish Mauser in the 6.5x55mm and sporterize the darn thing.
(1). You will spend less for this project than you would for a new rifle in your preferred caliber. The 6.5 Swede doesn't really give up anything significant to the 350 Rem.
(2). The 6.5 Swede doesn't give up anything to the 260 Remington either, and some folks have called the 260 a 6.5 Swedish 'Wannabe'. One gun writer said the 260 comes close to the 6.5.
(3). You can probably purchase 40 to 60 rounds of Sellier and Bellot 6.5 Swedish hunting ammo in 131-140 grain weight for the same price you could probably purchase 20 rounds of the 260.
(4). When you have finished with your project, you will have a custom Swedish Mauser, with a custom stock, trigger and scope setup that will outshoot any 260 all day long. 260s come in a lightweight sporter configuration, which figures the barrel to heat up after the second shot and throw your groups. Most of the lightweight sporters are like that, with the manufacturers claiming you shouldn't need the 3rd shot, so why worry (it doesn't always work like that). The Swede however, just keeps pounding them in there all day long and is known for its ability to do so.
(5). I wouldn't bother with a scout type scope mount, I just don't trust them yet.
(6). Your custom Swedish Mauser will always be a rugged military rifle, just with improved ergodynamics specifically suited to you, whereas your lightweight 260 sporter 'ain't'.
Just my 2 cents worth. Mikey.
(4). I'd repeat #4 just 'cause it's true.
