Re: which reloading press?
The current model of Co-Ax press has a longer handle yoke, and will clear practically any 7/8-14 die, even micrometer. For cases longer than standard magnum length, it does get a little tight seating a bullet, and the UltraMag is good for that.
The co-ax and UltraMag are both excellent presses. I like the features and design of my co-ax though, from the floating, snap-in/out die retention, automatic shell holder jaws, and flawless spent primer handling, to the over-the-top, down-the-middle handle motion.
