[QUOTE="Trickymissfit, post: 622346, member: 25383"] there are a few varibles in your quest for better concentricity. * just because the other rounds come out better dosn't mean your setup is all bad. Look closely at how the bullet contacts the seater stem. * take a once fired case and check the concentricty before resizing it. Then check it after resizing the case, but without a bullet in it. Check the O.D. of the case in two or three places along with the neck. You may have another problem that is giving you error. Measure the neck runout in the I.D. and O.D. and compair the high points (location) and low points. * Assuming the case is good and the seater stem looks good, then I'd hunt up a Forster or Redding seater. They are pretty much the same, but one is 33% more money Also you might want to hold the sized cases up against a strong light, and check them with a strait edge to see if the cases are actually strait, or have a banana shape. Look for a bulge just ahead of the band on the case O.D. Four or five thousandths here will often drive you nuts. The best sizing die for that case is from Innovative Technologies, and the best seater is a Forster. But even the I.T. sizer is ment to be used with a regular full length die most of the time. gary [/QUOTE]
