Square Deal B vs RL550B
When I bought my RL550B, it came with one caliber setup. dies and the complete conversion kit. I chose 9mm. I had previously owned a Lee press that auto indexed and that was one of the main reasons I went to manual indexing. Most progressive presses (including Dillon) that auto index, tend to splash powder out of a pistol case when actuated. I like to use powders that mostly fill the case so an inadvertent double charge would be obvious.
I also disagree that auto indexing is safer for the beginner. When you get that occasional 380 mixed in with your 9mm brass or, the small primer 45 ACP and your press “crashes”, it will be much easier and safer to correct the problem with a manually indexed machine. A beginner should start on a single stage anyway.
I also reload 5.56 and 300BLK on my 550 for Three Gun, and practice ammo. Cant do that on the SDB. Another great feature of the Dillon standard dies is that they can be cleaned without having to remove them from the press or mess up your adjustments.
The SDB and the 550 are close in price, but the SDB comes with dies and is auto-indexing. I think auto-indexing is a big safety feature for a new reloader.

I would not trust any factory to set up my dies. How would they know what bullet you are using and what the proper seating depth is? How would they know the proper amount of crimp, etc?Also, the SDB comes from the factory with the dies set up to load the caliber on the box. All you need to do is set your powder charge, load primers, and start loading.
I didn’t know that the SDB used proprietary dies. But if it does, that would be another “no go” for me. I have two pistols that have tight match chambers. A small base die is required in station 1 in order to get the cases to reliably function.Don't worry about the fact that SDB's use proprietary dies. The dies are Dillon, and great quality. If/when you upgrade, sell the dies along with the press.
