If you buy the lowest end Remington rifles, the SPS series, Cabelas has the blued ones for around $550 and the stainless for around $650.00. I didn't notice any sporter weight 308's, so if you wanted a heavy barrel to keep, you'd have to buy a police or varmint model. If you were going to scrap the barrel,you could buy a 243 SPS for $550. Should be the same bolt face if all you want is the receiver and bolt. Personally I'd say scrap the factory barrel and blueprinting the receiver, and get custom target receiver that machined properly right off the bat. I think that's what I'm going to do.
