[QUOTE="benchracer, post: 815341, member: 22069"] Yes, that is what I was asking. I was looking at the prints for the SAAMI/Nosler version of the 280AI vs the P.O. Ackley version and was doing some rough COAL calculations with the bullets I want to use based on bullet length, neck length, and desired seating depth. I had previously understood that if a case is necked down, the neck lengthens, and if it is necked up, the neck shortens. Because of that, I was expecting a shorter neck length than shown on the prints I was looking at. I have to admit that I am surprised to learn that necking up to .338 from .284 would produce a longer neck. Without the benefit of actually having done that, I am having some trouble getting my head around that. [/QUOTE]
