It looks like I am having some run-out problems with my 25-06 loads. My cases are neck sized and I'm using a Lee die to seat the bullets. I don't have a concentricity guage yet,waiting on the Hornady tool to become available) but I can see a little wobble when I roll the loaded rounds on a flat surface. The Lee seater die doesn't seem to control the bullet very well when it seats. I've been looking at the Redding competition seater die or the Hornady new dimension die and need some opinions. Why is one better than the other? The price difference is substantial $80 vs $20. There is also a Wilson Chamber type seater die for use with a hammer or Arbor press. How well does that work?
