I just recently bought a Rem 700 VTR chambered in .308. I've only shot about a hundred rounds through it and can already tell my money was well spent. I do want to start to "upgrade" it. I'm satisfied with the stock and optics, but I have heard a new bolt would be a good idea. Any feed back or suggestions? Does a bolt make that much difference? I've searched around on the web and most complete bolts I found run about $250-$350. I'm wondering if the cost is worth the increase in accuracy.
