Gustav, are you using Lee dies? Or, are you using the Dillon (key advantage is the removable core for cleaning?)... regarding die choices... is there’s an advantage to a micrometer seating die for pistol re:
For .357/38 yes I am using a full 4 die carbide set from Lee. I think I paid $40 for it brand new from a local store. You can find them on any of the online distributers of all things guns/reloading, usually with free shipping. As opposed to Dillon's $70+ dies and can only buy from their website which charges me $15 shipping for anything you buy lol. The Lee dies come with their powder through expander, which is set up just like Dillons, except you can use it by itself, with a funnel, or with one of the two auto throwing powder measures they offer (auto drum and auto disk). You just screw out the hex top piece and screw in the auto drum powder measure.
For 9mm I do not use Lee dies. I have RCBS dies from 8 years a go when I first started loading 9mm. I use the resizer and the seater out of that set. So to use the Lee Auto Drum powder measure I just bought a 9mm powder through expander off Midway for $16 I think. You can buy the individual dies just like any other company. So now I resize with the RCBS, expand/powder with the Auto Drum, and seat/crimp with the RCBS seater. Worked great the other day, knocked out 500 rnds in about 90ish minutes. Just relaxing listening to music with a buddy.
In the pic below you'll see 4 dies. I had some WCC 9mm cases that the primers were being very stubborn and ended up bending my RCBS decapping unit....which I think are made poorly anyways. So I used a Lee decapper in station 1, resize in 2, powder/expand in 3, and seat/crimp in 4. The Auto Drum allows you to use any station to powder, which is the only way I could finish reloading another 200 rounds. If I had the dillow setup, I would have had to wait on a new decapping unit from RCBS.
As far as dillon dies go, Im sure the removable core is nice, but does not personally justify the extra cost involved. I have nothing against the dies, but after using the Lee Dies, I would not personally purchase Dillon dies unless I needed something special.
I would NOT spend the money on a micrometer seating die for any pistol caliber. OAL is not as finnicky for pistol and generally you're just trying to seat to specific OAL's for functionality. I've never heard of anyone using standard pistol calibers in standard firearms adjusting seating depth for performance. POSSIBLY adjusting of seating depth for lever gun functionality, but not accuracy. And even then, you can still precisely adjust seating dies without a micrometer.
Speaking of the Jafer toolhead...as I was typing this it came in the mail. $28 shipped to my door, made in the USA, CNC machined out of 6061-T6 Aluminum.
Sorry for the long post, hope this helps
