Hi gang I am new to the forum and have some technical questions on Rifle brass cocentricity. I just purchased a new Savage 12BVSS in 22-250 and 200 new WW Brass cases. I also have a new Redding Competition Bushing type die set. (Neck die, Body die and Seating die) I did the following to the unfired brass, Pocket uniform, Pocket de-bur inside, chamfer necks inside and out and sorted by weight. I did not turn the necks and would prefer not to. I did run them through the Neck sizing die with the appropriate bushing (.249) Neck OD less .003 as recommended by Redding. This operation just barely affected the necks if at all. I have neck runout of +/- .002 to .005. Here is my question: How can I get the brass closer in cocentricity? I would like to have no more than +/1 .001 or less if possible. I loaded 20 rounds very carefully and the bullet runout is not acceptable. I have ordered a Redding Full length die, will that get the cases lined up better. If I fire the cases will they become more concentric? Any comments would be greatly appreciated! gun)
