So 550 or 750?
I’m wanting a progressive but dont need to load 1000 per hour lol
Want simplicity and i dont want to have to tinker with it

Very happy with my 550B. Also have a RL1050, kinda overkill for me. The 550 does everything important except for primer pocket decrimp. Don't especially need case-feed and auto-advance.

As a racetrack enthusiast said to me "speed costs money......how fast do you want to go?".

Does it come 100% setup running perfect or do you have to tinker with it? When changing calibers or primer size do you have to tinker or is it 100% plug and play?

I have a 650 and am looking at getting a 550 (keeping the 650). The 650 with case feed is great for volume, but my understanding is changing primer size is kind of a pain. I think for someone who loads multiple calibers, a 550 (or better yet, two 550’s) would be the way to go. Don’t get me wrong, I live the fact that a 650/750 can crank out nearly 1,000 rounds an hour, but an easy changeover is probably more important.

I have a single stage (everyone should) to work loads up. Then I set the progressive for my volume load and leave it. If I want a couple hundred rounds with a different bullet or load, I just use the single stage. Of course, this means I have a set of dies for the single stage and another for the 650. The 550 is also easier for working up a load if you lack a single stage press.

The 550 does not come fully set up. But things like adjusting a powder measure, setting your sizing and seating dies, are not progressive press-specific.

Once set a 550 doesn't need adjustment unless you change components/cartridges, powder charge, bullet seating depth, etc.

I've had a Dillon 550 for almost 40 years. I load all of my 6 pistol cartridges along with my .223 and .308 rifle cartridges on it. I've had a Rock Chucker press on my bench next to the 550 from before I bought the 550. I work up loads on the Rock Chucker and load all of my other rifle cartridges on it.

I have only one set of dies for each cartridge, and freely move the dies between presses because I inserted a shim under the die holder on the Rock Chucker press. A die adjusted for the 550 will have a gap between the top of the shell holder and the bottom of that die in the Rock Chucker. The shim is a 7/8" flat washer ground to the thickness of the distance between the top of the RC shell holder and the bottom of the adjusted dies from the 550.

My next Dillon will be a 750. I like the auto index feature for me.

never used the 550 but from advice here on the fire i went with 750 and love it like everything once you understand how it works it's a breeze the change over is very simple even the primers.

might want to you tube videos of each and see the differences
