Thanks for the reply woody.
I did see that alteration on the Brian Enos website, looks like a pretty good solution too. However, after looking at those pictures and comparing to my press, it appears I have an older style 650 that has the primer cup mounting bracket holes in a different location than on the newer ones. On the new style there are two holes for mounting the primer catcher cup, located in close proximity to the spent primer hole, which allows you to fasten a bracket holding the flared case, or ferrule, or whatever, to attach a hose to.
Looks like Dillon has addressed the spent primer issue by redesigning the whole platform and spent primer cup mounting system.
I agree, the Dillon is a rock solid press, and I really do like it. It's loaded many thousands of rounds of ammo for me with very little problem, other than some used primers on the floor.
I did email Dillon tech support about what it would take to upgrade my machine to the new style. Hmmmm... maybe this is a warranty issue :)
Thanks Dillon, your customer service really is second to none! I received your email today and sent you my address. I'll be the guy anxiously waiting by the mailbox....
