Last summer my neighbor offered me a box of stuff he no longer needed for $200. In that box was a Forster Co-Ax press, in almost like new condition. I have been playing around with the idea of replacing my 50 year old Herters press (i have three of them) and today I got the Forster out of the box and was studying it. After watching a couple of videos online I have a question regarding priming. I understand the process, but am not sure if the tool will allow you to prime different sizes of primers without changing the little head in the tool, or how to change it, if its necessary. He was loading for pistols and I primarily load for rifles and use another press for pistol. So I am not sure that I can load for large rifle primers with the way it is currently set up. I don't want to bolt it down until I am sure that I can use it. I know someone here can help me out.!!!! Thx
