Well, I filled my first bottle with spent primers so I am probably "qualified" to comment more at this point.
This thing is cool, as cheap as they are I might end up with another one.
I mainly bought it to swage primer pockets, but am thinking of other things to do with it. For decapping and swaging 9mm it just rocks. I currently have a mounded full 5gal bucket of brass I am working my way through. A while back I bought a bunch of fired cases really cheap, and they were all heavily crimped, and now all of my brass is poluted with them. So I think I am going to work my way through this bucket and then decide if I need to do it, or subsequent loadings could just be fine, once the main batch is vetted (I hope I live long enough, there is a shitload... J/K).
This morning's experiment was to trade the decap die for a sizing die. As fast as it is, it seems a little goofy to me to run something through there just knocking the primers out. I also recently had a Lee 9mm die separate the carbide insert from the body, so I bought a new one (and put it in the press) and then used JB Weld to glue the original one back together. Since the primers will be out, I am trying the idea of lubricating the 9mm cases, if I can size them with not much more effort than decapping it will make things effortless when loading. So far I have done it without tumbling, but am going to try a batch I ran in the F.A.R.T. for a quick 30min, if you were really frugal you could probably do this with just water. This also makes it simple to catch a case with a stone in it without disrupting the indexing on the 650. Also when a case sizes too easy it is probably a 380 and it is easy to pull it out.
At least for 9mm I think the 25 pound swaging guidance seems a bit like a bunch, I set it for lighter.
So far I got it flying for 9mm but 5.56 seems a little more touchy to get right. Another problem is I have been trying to size the cases without expanding the necks and the recommended punch is a little too thick. I plan to experiment with something with a little smaller diameter, I think coupled with a bit less pressure might be an OK balance.
This thing might displace my 550, maybe. I am starting to think the 650s will be doing all the 9mm, 5.56, 300BO, 38, and 45 I will need, and do I really need to load 357 and 44 rpogressivly? Especially if I can size, decap and flare in an APP? If I ever do actually get a 10mm or 38 Super will I need to load them progressivly? I went ahead and ordered the extra shell holders, but they are back ordered.
I am experimenting a little on what bench height this thing needs to be on. If it were just decapping it could be clamped to the armrests of an Adirondack chair...
