Check your telephone directory for a store that might have at least one of the presses to look at.
When Dillon first came out, they sold directly to the end user and no store had one on display.
As I said, I taught my son how to reload on the Hornady. The press is easy to operate and watch each function at each station.
Note: This is strictly my impression, but Dillon tends to pack their dies closer together (or it looks like they do) and the presses, to me, look complicated. They aren't, but that is how I saw them. Because of this, the machine is more of a mystery. The Hornady, in comparison to my impression, is more open and easier to follow each step.
Any of the machines are excellent and they can make ammunition that is as good as possible.
Heck, some people are completely happy with their Lee 1000 and LoadMaster and the ammunition they produce is excellent.
I just get irritated that some people take up bandwidth to say: "Buy xyz, it's the best" without any reasons.
