1. Trigger job or Replacement of factory trigger to allow crisp 2 to 3 pound trigger pull. Replace factory firing pin, spring and shroud.
Additionally the following should be done one step at a time to incrementally improve accuracy of rifle without breaking your bank account.
2. Steel Bed Action, free float barrel. (Good point to consider aftermarket stock from McMillan, etc if you are not pleased with factory offering.)
3. True action (Blue print) to square and align mating surfaces of bolt and barrel.
4. Replace factory barrel if it doesn't perform with Lilja, Hart, etc. (This should be done if factory barrel doesn't shoot 1" at 100 or smaller after break in.)
5. Upgrade scope if required for accurate and repeatable W/E motions and parallax adjustment.
The goal is to provide at some point in this cycle a .5 moa rifle (1/2" at 100 yards five shot group.)
--OR--
You can throw away everything but the action and put C$6000 in it to start with!
