As a first reloading press , I believe a single stage is the ONLY choice. From ther it is simply a matter of brand or size pick. Maybe look to the future: are you thinking of a 50BMG at some point ? Then buy a press that will accomodate that case, but still a single stage. I have had a progressive set up, and there is a LOT going on , just a bunch of potential for missteps, everytime you move the handle! Also, for precision shooting and loading, you're probably going to weigh every powder charge anyway. My first press was a lower price point RCBS single stage, and I still made alot of mistakes. My opinion only.
I don't plan on reloading 50 bmg ever. I don't need it. 270 mostly. Maybe 223, 243, and 6.5 Grendel eventually.
I spent 4 months working on autodrive-ran Dillon Super 1050's every single day... As long as you don't try to run it too fast, and you learn all the tips and tricks to properly setup and gauge the shell plates to avoid feeding issues and indexing issues, you'll be ok. But trust me, unless you're ready for a beginner nightmare, do NOT buy a progressive to start out with to learn the basics...Those machines have WAY too many moving parts to learn how to calibrate and gauge when you're first starting out reloading.Dude, buy a Dillon! If you ever have a question they will walk you through it right on the phone. I have a Dillon 550B and use it as a single stage press for precision loading though. It rocks for doing pistol loads as a progressive.
