Changing to that Lee Cutter and Spinner Stud is what I did. From new, and from various purchases on EE, I ended up with a couple or three spinners and cutters. I have to buy the shell holder / case length gauge one at a time for each cartridge. At that time, I thought it was a "slick" replacement for the crank style cutter that I was using, which needed a pilot for each caliber that I would trim. So each die box here ends up with the shell holder for the press / priming tool and a shell holder and gauge for that cartridge for that Lee trim system. In use, I roll my cases on a Lyman lube pad to lube them with RCBS Case Lube-2, then size, then into that Spinner Stud that is in a battery drill - trim to length, chamfer and use a wet rag to wipe off that lube - then on to next case. I usually process batches of centre fire rifle cases like that - about 100 cases (or less) per session. De-priming, annealing, tumbling was usually done in a prior session - in larger batches. That is about as long as I can stay interested in it. Seating primers, dispensing powder and seating bullets is usually done as a separate session. I've had too many "klutzy" experiences of dumping a loaded round over other open loaded rounds - so I tend to seat the bullet immediately after dispensing the powder into that case - I do not like having multiple cases with powder in them, but no bullet - I have knocked over too many or spilled stuff.
As you acquire odd-ball or obsolete cartridges, you likely have to make some of your own tools, or alter from something else. I could not find a case gauge for 9.3x57 to buy - so chucked one for 9.3x62 into my lathe and cut it to length. Same with the Factory Crimp Die - I do not think they make one for 9.3x57 - so I will be cutting down one for 9.3x62 when I get to that one, again. If I still had the crank type trimmer, likely would not be an issue to trim 9.3x57, since I would have the 9.3 pilot for the 9.3x62, anyways. And not all people use the Lyman "M" die, or a Factory Crimp Die, so maybe there is ways to get around using those.
For 28 gauge shotgun, I used an MEC machine - ended up with a Universal Charge Bar, so I set that thing for weight against my Hornady Beam scale - powder and shot cavities. I think I might have done only 200 rounds or so - ever. For 20 gauge, there is a Lee Load-All in its factory box - I opened that box to look at that tool, but never used it - so I have not loaded any 20 gauge, at all. There is a Winchester Model 12 in the mail on the way to me - I should see it this week - that will be the first 12 gauge that I have had since about year 2000 - there is a flat of #7.5 lead shot ammo for it - I am not set up at all for re-loading 12 gauge - not sure that I will.
I do find it a bit more of a challenge to find a "pressure tested" shotgun load recipe, that uses the hulls, primers, wads and powder that I have on hand, or am able to get, for sure - I just do not know enough about it, to know what stuff is "close enough", or what stuff can be substituted from the "recipe", versus what has to stay the same.
