Is the RCBS Case Master or Hornady Concentricity Gage worth buying? I'm thinking about getting one but I don't know which one to buy. What do you guys think.
I have the RCBS Case Master and like it very much. It is a little trickier to use than the Hornady but it does more things. I use it for concentricity, runout, headspace, shoulder datum checks and other stuff. It is all in the setup but gauge is accurate and flexbile.
