I have been reloading for several years and would like to get a good set of dies to improve my reloads. I am looking to cut down on the chance that the reloads have runout and uneven neck tension. I know neck wall thickness plays a part and I plan on culling the brass that has that problem. So what set of dies would you get? RCBS Gold Medal or Redding competition? Thanks for any help you can give me.
