Dillon 550 is the way to go. I think the 550C is the latest model.

That said the RCBS Rockchucker can be a handy thing to have around. I've had one for years. Other than for loading some rifle I use it mainly for bulk depriming and sizing range brass. I do use it sometimes for working up maximum loads. That way I'm careful, slow and deliberate and weigh each charge.

For that matter a Lee Hand Press is a great tool for certain occasions. I just checked and the Hand Press has gone up in price. They're not $15 bucks or so anymore.

My only other experience with lee presses is one of their progressives, which IMHO was trash. But that was quite a few years ago. It would crank out ammo like lightning, when you weren't working on it, which was most of the time.

I have a Dillon 450 and a 550. I've had the 450 since about 1982. Both are great but you want the 550 unless you get a real steal on the 450.
