meth0d,
What are you planning to do with the rifle? Bench rest or just a plinker? What are you shooting at 200 yards? Whitetails or prarie dogs? Your rifle might be good to go just like it is.
I've got a Savage model 10 and a model 11. Both in .308. The model 10 came with a proof target from the factory with three shots going into .285". It's got a really great trigger (IMHO) on it. When I do my part, off the bench, with good ammo, I can keep three shot groups within an inch. Like you said, "...more accurate than my abilities..."
Shortly after I ordered the rifle, Savage announced the introduction of the Accu-Trigger. I called the custom shop and asked if my rifle could be made up with this new trigger. I was told that my rifle had already been started and that the receivers were different between the two trigger systems. Like I said before, the rifle has a great trigger and I'm happy with it. The trigger breaks well at three pounds and passes the drop test. I mounted a Leupold M8 2.5 x 28mm IER "Scout Scope" on it and chose to break the barrel with the "shoot-one-clean" routine. It is not a sniper rifle, but I've consistantly hit full size pepper poppers with it at 400 yards. That is not the purpose of the rifle, but it is good to know that we can do it if the need arises.
My model 11 has the Accu-Trigger on it and it is sweet!
I think that you should save your money and not buy a bunch of parts (barrel, stock, and trigger) until you find out what you can do with the rifle as it is. If you don't like the trigger, take it to a gunsmith and have him work on it. While he is in there, he might find a thing or two that he could clean up like the bedding or barrel channel. Your scope is fine as long as it is serviceable. Just check to make sure it is mounted correctly.
Buying a bunch of expensive aftermaket parts won't help you sight, hold, or squeeze the rifle any better. You would be better off to invest some time in practicing the fundementals of marksmanship. If you've got the cash, take a shooting class with the rifle. Unless of course you are just one of those guys who like to tinker with stuff!
Bottom line- dry fire a bunch and save you money for more ammo!
