The question really starts with a tight neck chamber or a standard neck chamber. What kind of clearance are you looking for with a tight neck chamber? It requires you to have a ball mic a neck turning tool, know your neck dia of your chamber and be able to identify the heel dia of the flat base bullet you want to set up the brass for. I shoot some barrels with .0005" clearance on a side for a total of .001". If you are shooting a standard neck chamber then you do not want to turn necks, you will only add more slop to your loaded rounds. The real key to accuracy is in the seating die. You want the straights ammo you can make, never increase the run out, you need the best dies you can find. This of course is assuming that a top notch gunsmith did the chambering in a first class custom barrel and you have a top notch action and the stock is well bedded. There are many pieces to the accuracy puzzle and they all cost big bucks. Is all of this important for a hunter? Let your own happiness be the judge, and pocket book.
