[QUOTE="nheninge, post: 271191, member: 13085"] Well I necked down as we discussed and I got quite a few good cases (< 2-3 thou case runout), and some with VERY increased case runout (10-12 thou even). The best I can see is that the redding comp S type neck sizer does not give quite enough case support on new brass and allows the cartridge to move around in the sleeve loosely. Redding comfirmed this possibility with a phone call. The increased runout started when sizing to 0.333 to 0.329. Using a Forster press with floating die. My questions are: MBrown, do you notice this effect? Are there any other dies that might give a little better case support with new brass? Any experience with Wilson dies for necking down new brass? Fire forming should straighten these up followed by FL resizing, but it would be nice to get them all as close as possible first. [/QUOTE]
