[QUOTE="bigedp51, post: 1588203, member: 28965"] The bushing size and using the expander also depends on if you are neck turning your brass. If you Google Redding bushing FAQ there is much more information like the neck thickness variations below. [B] Tech Line & Tips (FAQs) [URL='https://www.redding-reloading.com/tech-line-a-tips-faqs/140-bushing-selection']Bushing Selection[/URL] [URL]https://www.redding-reloading.com/tech-line-a-tips-faqs/140-bushing-selection[/URL] [/B] [I][B]"If the neck wall thickness varies more than 0.002", it may be necessary to use a bushing a couple of thousandths smaller than your calculations indicate, and then use a size button in the die to determine the final inside neck diameter." [/B][/I] NOTE, in the same Redding bushing FAQ it also tells you if you reduce the neck diameter .004 or more you can induce neck runout. Meaning how much the neck diameter is reduced from its fired diameter. And if the necks are not turned the runout will be even more due to the uneven neck thickness.
