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.
Just have a competent gunsmith do a good trigger job for you and that will be a huge help.
If you are handy do a good bedding/float job on it yourself, if not have the gunsmith do that as well.
Take care of those two items right there and then find a load that works well in it and you should have a very nice precision rifle.
You can do a lot to stiffen the stock as well by digging (find a friend with a router or go to a cabinet shop) out a good deep channel in the fore end back to the recoil lug and filling it with Devcon and Steel Shavings or you can mix the Devcon with lead shot to add additional weight. If you also lay a piece of stainess rod or even aluminum in the channel along with the epoxy/metals mix it will become extremely rigid.
