Any brand dies will work in a Co-Ax (Bonanza). I'd just buy any carbide dies that fit your preference. You shouldn't need any specific shell plate. The Co-Ax is universal.

One thing to note. Some people find it easier to use the Forster rings on their dies in that press. Forster rings are quite large, and seem to fit the slot that holds the die better. You can buy the rings separately to replace your RCBS, Hornady, or any other 7/8-14 die.
