I finally got my Hornady set up so I decided to start loading some 300blk. I am having such issues with the primer systems that it is driving me nuts. Each time I raise the ram the primer slide moves back but consistently it would not come forward when I lower the ram. Sometimes it would slide forward without the primer. Sometimes there would be a primer. I tried to polish all the contact surfaces but that does not seem to help. without the primer tube the slide goes back and forth as expected. Anyone having this problem? How did you solve this issue?
