[QUOTE="Greyfox, post: 802169, member: 10291"] Having gone through a few different lots of Norma brass in my 300 WM, if have found it to be very consistent in neck wall thickness running .0145". Great brass, but it should be for the price. With once fired cases I will neck size only for 4 firings, then use a body dye and FL size to .002" shoulder push back. All dyes used are Redding. I have found neck alignment with the case, and bullet run out to be consistently less then .002" by using a Redding S dye, with the busing sized to .002" of neck tension. I will back off the bushing knob on the S dye a small fraction of a turn so you can faintly hear the bushing click due to slight looseness in the dye. This seems to allow the bushing to float and follow the fire formed neck. I'll use a very small amount of Imperial wax on the neck. I have not seen the expander on my specific dye cause alignment issues but I remove it anyway. I will anneal the cases after every 4-5 firings. I have used this approach for several belted case cartridges I have loaded for and it seems to produce very good accuracy, ES and case life. IMHO. [/QUOTE]
