Press is mounted to the bench now, it came with 2 crossbolt lock rings. After seeing how those work and looking at the fitment of the lock rings I was going to attemt to modify I have decided to bite the bullet and buy the Forster lock rings. The hex shaped lock rings just dont fit the press nearly as good and there is way more contact area with the round style. Though I did recieve sound advice here, I had to see for myself before spending my hard earned cash for them. Thanks to all who replied.
You will be very happy.... And accurate..
