[QUOTE="woods, post: 862507, member: 6042"] If you get a custom die, then what happens when you get brass that is thicker or thinner. Essentially your chamber clearance would change. A tight neck enables you to outside turn any brass to get the clearance you want. IOW if one box of brass is .015" thick and you have a custom die that gives you .003" clearance, then when you get a box of brass that is .014" thick your neck clearance just increased by .002". Not a big deal but for a control freak it makes a difference. IME most brass will have a thick and thin side. General consensus seems to be that if you have a variance of over .002" then discard or set aside for other use. With a tight neck you can do a complete turn (rather than just knock the high spots off). Theoretically then the off center neck will be fireformed by the chamber into alignment with the case body. IOW if I were going to order a rebarrel or custom gun (planning on a 243AI soon), I would get a box of brass I intended to use, measure it and make sure that I could do a complete outside neck turn taking of at least .001" and probably .002" all the way around. That way I could be sure I could get to the exact neck clearance I wanted [/QUOTE]
