[QUOTE="misterc01, post: 1912427, member: 109160"] I start with checking my brass after tumbled with an RCBS Precision Mic to see where I am before starting. I then size it with a Hornady Match bushing die to get the initial measurement to .002 under SAMMI Minimum. I agree with Savage 12BVSS about I using a seating die with a sleeve - I use a Forster Micrometer seating die, and it made a world of difference. My end product is usually at or very close to where I want it as far as run out. Some use a co-axial press and believe that also helps. I then use a Hornady concentricity gauge to get it as close to 0.0 as I can, and call anything under .002 "good enough" and that works for me. [/QUOTE]
