What is the best sniper style stock upgrade for a Savage 110 long action? I like the MacMillan but too expensive. Are the Choate an good? Anyone know of any others? Most I see are short action. Also....my rifle has plain factory barrel...should I invest in a heavy barrel or is it not worth the cost. Is there a bolt handle replacement for the factory one? Maybe something larger? One last thing.....What is a good replacement trigger for the accutrigger and should I replace it? Thanks!
