Over the last three days I have mic'd, sized, mandrel neck sized, and turned 300 cases in 6CM, 6.5CM, and 6.5PRC each. I can tell you without reservation that bushing dies don't help your runout. Somewhere in there I have a Forster die that sizes new brass case webs .002 and a regular old RCBS die that kicks out brass with .0005" of runout. I like micrometer dies, sizing dies I'm moving away from bushings if I can. My 6.5G ammo comes out damn good with a set of Forster dies. Lee dies still look like they're chambered with a hand drill.
