[QUOTE="MontanaRifleman, post: 808806, member: 11717"] I'm no BR guy but I've read a lot of BR guys have adopted FL sizing. I switched back to FL for consistency and because I didn't think a 2 step sizing process (neck and bumping with body die) was conducive to good concentricity. Didn't have a runout gauge early on but when I got one I found my runout was down to less than .001 when I FL sized and lubed the inside of my necks. With 300 RUM brass I was bushing neck sizing and found I had to body size each time after about 3 firings. That didn't make sense (2 step process) so I went to FL sizing and was really pleased with the results. Some of my best groups came from a Sendero 25-06 in which I did almost nothing with the brass other than clean the pockets and FL size with a Forster sizing die and seat with a Forster BR Comp die. I got a few 2's and a lot of 3's and 4's. I've got a couple sets of custom bushing FL sizing dies coming for a couple of semi custom builds. The plan is to bushing size the necks 1-2 thou smaller than the expander and use the expander to push any irregularity outside - no turning. I'll have about 2-3 thou neck clearance in the chamber.
