Re: Good Caliber
If that BVSS is a good deal I'd jump on that , you can rebarrel it to what ever you want even the 308 with a simple barrel and bolt head change and the mag box if you want it to be a repeater , you can get a great trigger from SSS for under $100 and their lug for about $25 or so and the BVSS stock is a good solid platform to shoot from.
And later if you want to build an ultra accurate custom you can use that action and have the barrel setup like the Rem's without the barrel nut.
I've seen several BVSS's that shot under 1/2" reagularly and one was a 300Win mag.
Like I said if its a good deal jump on it and spend your leftover money on some good glass , rings and bases
