Yes, you are right. However, please notice I said "Strong press". FYI, there are some strong presses capable of swagging bullets. Small hydraulic press could be also used, or vise for milling machines, to eliminate "belt". I had done (tool) for swagging, thinning, case rim, from .060 to .038, creating .455 Webley Mk I cases from 45 Cowboy Special, or (shortened) 45 Schofield.Sorry for the long delay on what is close to a zombie thread but I just saw your response.
I was afraid someone will try this and ruin some equipment.
Don't care where you read it that does not work . Good press bad press carbide die super lube whatever , won't work.
The cartridge will size nicely till you hit the rib . Dead stop. That is solid brass and will not compress ,not even little .
If you pull it out there it looks like a belted mag rifle case.
If you try to force it thru I can guarantee it will get stuck hard enough to rip the rim off trying to extract it.
In my case it actually pulled out the carbide ring also!
Back to the part about looking like a belted case. That's where the lathe comes in , turning that belt off.
I have danced this dance and that is simply the facts.
If you believe you have seen Taffin write something different I would like to see a reference because fellas are gonna lose dies trying.
