Back in the day, I started with a single stage press then obtained a Star, which used proprietary dies for handguns only, I loaded .38 Special and 45 ACP. .
The star was replaced with a Phelps progressive loader that was set up so you could use RCBS dies and also reload rifle cartridges.

The Phelps was replaced a Dillon 450, which was upgraded to a 550 then to a 550B, which I still have,
I also have two XL650 Dillons. Once i got into the progressive machines I never looked back for volume reloading.
However still bolted to my reloading bench is the RCBS Singe stage press that started al of this.
I use it for load development 50 Rds or less and for my target rounds for my rifles.
