I started on a friend's 550 and he had a 650 on another bench. He said now that you have the hang of it try the 650. I bought one a few days later. Loaded on it for 5 years, traded it for a few really nice guns and drank the cool aid early when Mk7 released their Evolution. The Evo is like a 1050 on steroids....but I have a soft spot for the 650....great loaderMy wife bought me a Dillon XL650 as my first press a couple of years ago as a Christmas present.
She spent a bit of time researching, and got help from a buddy of mine down the street that reloads.
Bought it setup for 9mm, with a casefeeder.
My buddy and my son helped me set it up and showed me how to use it.
My first couple of hundred rounds were a mixed batch, some good, some bad, some "meh".
After that I had a pretty good idea of what I was doing.
I load lots of 9mm, and smaller quantities of .357Sig, .38Spcl, and .357Mag - I'm about to add .45ACP to that list.
Even with the swappable toolheads, I found it was a pain to swap to one of the other setups only to go right back to 9mm.
I had the room, I had the money - I bought another pretty much identical 650 a while ago.
The original is setup on the left and always used for 9mm, the other is used for the other loads.
Last week I ordered a large primer unit from Dillon, as soon as the backordered dies come in I can start loading .45ACP.
I read lots of people saying on different forums that you should learn to load with a single station press.
Maybe that's true for precision rifle rounds - I didn't find that to be true for what I'm doing - cranking out decent pistol rounds.
I really like the XL650.
