3 main things to look at. If the rifle has a factory synthetic stock it will probably need replaced, the action must fit tight into the stock without flex and a free floated barrel that does not touch the stock is best for consistent accuracy. Boyds makes some nice laminate stocks for many different rifles at a decent price. Next item would be the trigger it is very hard to shoot accurately with a 6 pound creepy trigger, just shoot a browning BLR rifle and you'll see what I mean. Timney aftermarket triggers run a little over $100. 3rd is the Ammo definitely consider reloading so you can find shoots best in your rifle. Powder charge weight and bullet seating depth can greatly affect accuracy, once you find what your rifle likes with a good stock and trigger you should shoot 1/2" groups all day long if you do your part.
