In all fairness to the Co-Ax, one of the things that gets it a bad rap really is not the presses fault at all. Because it is so easy to flop a die in and out of the thing, guys think that's "all ya gotta do"....set up a die for a specific headspace case length and run that brass and they come out fine. A month later with different brass....flop in the "adjusted" die and run them to resize, only to find that now it is not sizing the same length as before. It is surprising to find how many "reloaders" don't get the whole spring back and annealing thing. This same issue affects the T-7 when setting up dies and leaving them in place...same die, same set up, different sized length. But, different because of the brass, not the press or die set up. I know two guys this year that abandoned their Co-Ax presses for this reason. Once realized, their comment was, "well if I gotta set the die every time what's the advantage???" In that context none. Anneal your brass dude...you should be doing this anyway.
