[QUOTE="MagnumManiac, post: 1138493, member: 10755"] Bart B, I know you are very knowledgeable, but your definition of what FL sizing is and what you are actually describing, are two very different things. FL sizing is reducing the case back to SAAMI/CIP minimum dimension, so the case will fit in ANY chamber, what you are describing is PARTIAL FL sizing, the two are not the same. I do something similar with my loading for hunting, but I use a body die, then size the necks with either a modified neck die and expander, or a dedicated neck bushing die. It depends on the brass I'm using as to which method I use. Strangely, contrary to what many believe, my comp rifle cases get Partial FL sizing in a Forster style FL bushing die, are annealed after EVERY firing and get .003" bump to the shoulder. Accuracy is better than neck sizing and using a body die separately. To the OP, if case life is short, you're probably pushing the shoulder back excessively, try adjusting your die OUT, size a case, until it feels snug on bolt closure, then adjust IN 1/12 of a turn, this is approx .003" adjustment.
