I had an old C&H press that I liked as a kid, and graduated to a CO-AX and never looked back. I could see the argument about switching the shell holders for smaller to large cartridges, but I don't do that enough to warrant a complaint. I HAVE had the springs take off when doing so as if they were alive...no fun. But I do like my CO-AX and am not wont of another press.
As a side note, recently I loaded some 7x57 rounds with a brand new box of Win primers. I use a hand tool to prime, so contamination was NOT the issue. I had one not fire, and all others did. I just can't help but thinking I'll find the second when the deer of a lifetime is standing before me. Any ideas?
