[QUOTE="Trickymissfit, post: 982561, member: 25383"] most guys will be doing it with an O frame press, and when I did use one I used the method that Sierra used to have in their manual. But I took it a step further, and put a shim between the base of the die and the shell holder. Loosen the jam nut and run the ram into heavy contact with the die. Then while under pressure, retighten the nut. In my case I used a fender washer that was ground parallel. With the Co-Ax, I made a similar washer, but thicker. The hole is about .50", and the O.D. is close to 1" diameter. The thickness was about .025" thicker than the shell plate. After I reached the size, I removed the shell plate. Then place the washer in place of it, and brought the die down to meet it. Then loosen the nut, and retighten it. The O frame setup is easier, and could probably be done with a piece of shim stock. I might add here that I never trusted the typical shell holder, but saw improvement working off the top just the same. gary P.S.; I don't own a Sierra manual anymore, so I don't know if this method is even in there anymore. It came out of a manual published in the mid 1970's. Hornaday doesn't say anything about it, and leaves one to assume the die is square once it's threaded into the frame! [/QUOTE]
