Go Blue!
First let me state what I will be reloading for 9, 40, 45, 223 and 308 , some 22-250 and maybe some 357 for a revolver.
You raise an obviously contentious subject in this group; I have to remind myself occasionally that as passionate as I may be in my beliefs, someone with a differing view is equally passionate in theirs and we quite proabably are going to have to coexist never agreeing.
That said, I'll offer up my opinions. I'm a known Dillon zealot. I have zero experience with the Hornady tool. Mine is a 450, the predecessor to the 550 and 650 line. It's been in *constant* use since 1984. I've never upgraded mine beyond automatic primer and powder feeds. No interchangeable toolheads, no automatic indexing. I have a bit of experience with a buddy's 650 with casefeeder.
I actually like manual indexing vs. auto. Same principles apply for me regarding case and bullet feeding. I think it satisfies my OCD with the more hands-on, up close and personal routine. I pay more attention to detail in the process. Auto-index can poop out more rounds per hour, but with good staging of components, I can't sneeze at the 400-500 rph rate I can crank out. I also think when something goes awry on the autos, it's more time consuming and complicated to reconcile. Obviously, I'm a simple person; simpler seems better. I started with single stage reloading long before a progressive entered my picture. My buddy started with the 650 and knows no differently. He is as completely satisfied with his process as I am with mine. And I will admit that he loads all of our 9mm because some of the tedium of that small round seems to reconcile itself on his press.
Because I'm basically cheap, I've never upgraded to the removeable toolheads because there are ways to ease the pain of caliber conversion without the expense or storage bulk of preset toolheads. The Dillon powder measure can be a pain in the ass for a variety of reasons, not the least of which is setting the drop. I have 4 powder slides for mine, 2 each of large and small, one is permanently set to drop for my .223 load, one for .45 ACP (my 2 highest volume rounds), and then one each for the other dozen or so calibers I load. I do need to order a couple more. Powder dies at $10 apiece can be dedicated to caliber specific settings using locking die rings, then just screw on to the press, drop in the powder funnel and attach the measure with the correct slide inserted. I've watched my buddy do caliber changes with extra toolheads on the 650. My way takes an insignificant amount of extra time, and costs a pile less.
I have personal issues with reloading rifle cartridges larger than .223 on my progressive, so do most of my 22-250, .308, .30-'06 on the Rock Chucker. Some of that has to do with quantities involved being on the small side, some is the issue of the non-metering powders I use, some with sticking cases in resizing dies and either tearing the rims off or breaking the shell plate (it was an old, well-used plate and Dillon replaced it for free, even though it was my fault and I offered to pay). The .308 and I have come to terms and the chosen load works flawlessly on the Dillon now. If I ever find a ball powder load for the 22-250 that shoots as well as my current one, I will happily load it on the Dillon. But rifle calibers for me need to be sized/deprimed in a separate step from the rest of the process so I can measure and trim first, so that's a single stage process anyway. Then they go back to the Dillon with no sizing die for primer, powder, bullet, crimp. I bit the bullet for Dillon carbide sizer for the .223 and literally all my real frustrations ended with loading that caliber. If .308 quantity ever escalates (like a new AR platform maybe
), I'll pay the price for that die as well. I figure that kind of expense is more justified than for toolheads, extra powder measures, casefeeders and all the accoutrements that, to me, seem nice but unnecessary to accomplish the task.
Finally, (you thought I'd never say that) Dillon has NEVER allowed me to pay for replacement parts, though I always offer to pay, in the 27 years I've spent trying to break this thing. They have completely replaced the powder measure system and the priming system that I quite literally wore out, as well as stupid things like springs that had no more to give. To be fair, other companies in the shooting industry have acted in kind (Ruger recently offered me an entire new stock for my M77, rather than sell me a $2 sling stud. No joke), but I get the feeling the guys at Dillon do it with a sly smile.
IMHO, you would be completely satisfied with either the 550 or 650.
Now, we will hear from the Red Team.
