Having used the Bonanza since 1968 and after experiencing many failures on other presses, I for one will never go back to another press.
Attempting to explain the Bonanza/Forster automatic shell holder It is like trying to explain some people, they have to be experienced as they defy description.
As to using the Forster Co-Ax press priming assembly works well, like everything about a single stage press while it may take more time it is deadly accurate in the way it seats the primer.
I obtained this particular Old Bonanza because the original owner had a stuck case and did not know how nor by the damage he left behind did not ask for or receive good advice into how to perform the following operations
1. Release the Shellholder assembly to free the cartridge from the grip of the shell holder
2. Remove the Die c/w the stuck case intact from the press.
3. once the stuck case the Die and the Stuck are out of the press the process of removing the stuck case is dependent upon your equipment on hand.

The Forster method
Either process will work well.
The problem as I have now discovered is when people are alone and without guidance the first time stuck case can cause panic and result in damage to the best of reloading presses.
I have spoken to Forster about this and I hope to see a detailed write up or a video on the process in the future.
Removing a Stuck Case from the Press intact and without causing damage to the press or the loading die or shell holder can be a bit daunting IF you do not have guidance.
This is especially true for the new reloader and panic sets in.
