Start by backing that die out all the way, then raise the ram and turn the die back in until it touches the shell holder. Then turn it back out about an eighth of a turn.
Size one fired case, then wipe the lube off and see how it feels when you chamber it in your rifle. If it's tight (and I can tell you it WILL be), turn your die back in a little more and repeat.
Be aware that turning the die in just 5 degrees will change the shoulder set back by 0.001 inch. Five degrees is a tad bit less than how far the second hand on a clock moves in one tick.
Keep turning the die in just a bit at a time. You're looking for that point where you perceive that the bolt is closing a little easier, which means perfect fit. Once you find that point, snug down that lock ring on your sizer and leave it there. If you want to measure the shoulder on a case that fits the chamber perfectly for future reference, then do so.
Setting up the die based strictly on measurements and disregarding the "feel" aspect will work , but you may be leaving some available precision on the table.
