This is my opinion......just change tool heads and go .....with my 650 example for 223....doing case processing one tool head to deprime...size ...trim...or deprime trimm ...then change up to load ....and same for 308........then gotta swage all the primer pockets....kinda working twice.....I know no big deal but ...you know
Mark 7....do all in one pass ...and if one wants ...auto driver ..bullet feeder ....
If you got or have a big pile of brass .....you can spend a lot of time to processes it and load ..... mark 7....cut the time right down
Just my thoughts .....as I have had like a big pile of brass and took me a month to do it all ...in separate stages...
It is an interesting concept if you are making "plinking" ammunition. If you are trying to achieve a higher level of accuracy, no I don't mean bench rest, I mean practically accurate ammunition. Then I don't know if this is the way to go.
All of the commercial equipment breaks it down into steps. For me, I process the .223 and trim on a separate machine and am still getting +/-0.002". Even guys who are running "commercially" on 1050's split up processing itself into two passes as the more things you try and do at one time, the more deflection, and torque that you apply across the tool head. For .223 then de-prime and swage on the first pass, and may bump the shoulder back a bit. Then on the second pass, they trim and set final headspace.
If you try and do all of this in one pass, it can change your swage depth, headspace, trim length just for processing, Then add in loading on the same pass and you start having variance on primer seating depth, bullet seating depth and crimp.
The MK-7 Revolution may be completely immune to these problems, I don't know, I have never used one.
