Changing a 45acp to 45LC
« on: December 27, 2020, 03:59:46 pm »
I see some dies for sale that have been re-stamped over the .45 acp and changed to .45 LC.  How is that done?
Not the stamping but the changing of the bore? Is that a hone? Or is it done with a super hard cutter in a
boring bar?
The carbide is hard so it must take a real hard tool to do it.
Thanks,

Greetings,

I lap Carbide dies to a larger diameter with a Diamond Hone.

Have you a link to the dies in question?

Cheers,

Dave

There is a head set up for 45 COLT  on e-bay now but I've seen other dies in the past.    (https://www.ebay.com/itm/STAR-MACHINE-WORKS-RELOADING-45LC-45-Long-Colt-Conversion-Carbide-Dies-RARE/143884169806?)I think that will get you there. They strike over the ACP with COLT and I assume adjust the die to size.
Just curious how it's done.
Thanks,

My personal 45 Colt setup includes a Lifetyme die where the "ACP" is over-stamped with "Colt".   I think it was done at the factory.    Maybe when they did the QC check on the size of the carbide ring they found it was oversized for 45 ACP. ??
