I've used one for several decades. Excellent press, but I always have a strong single stage press mounted next to it. If you use file-type trim dies, collet bullet pullers, primer pocket swage dies, or do much in the way of case forming, the Co-Ax is not the best press. Opinions vary, of course, but if you don't need a press for any of those chores, the Co-Ax is perfect. Priming apparatus, once set, works very well, but I usually prime with a hand priming tool.
