I recently acquired a used RL450 with a bunch of other stuff in an estate type sale. I haven't used it yet, but it appears to have the primer and powder system upgrades. I'd say it's almost the equal of the RL550 I'm currently using. Correct me if I'm wrong, but I was told that the RL450 does not have the provision for kicking out the loaded round and it will have to be removed manually.

I feel that either a 450 or 550 would be a great choice as a first loading tool. But I would not want to be starting out with my 650 and its auto indexing and non-stop primer feed.
