So, received my Comparator insert. It’s a Hornady, but that’s all that available at the current time. I have been following the case prep from the sticky here, “Brass Case Prep”. I think I got a bad insert. Isnt’t the mouth of the case supposed to fit into the hole of the insert? I have a 5-26 sized insert for 6.5/.264 diameter. Mouth of the case does not fit though. Bad luck on my part with getting a bad insert?
