Here is what I have learned so far (if you don't want the "full Monty");
Scope first - Spend (at least) as much on your bases, rings & optic as you do on your rifle.
Get custom target turrets !

Production rifle - there are many good ones out there.
Personal preference as to which "features" you like in a hunting rifle.

Hire a smith to "accurize" the rifle.
Buy a lot of ammo & targets.
