Hello guys,
It's to late now, but I have formed 32 S&W cases to 32 Colt without the need to turn the bulge off.
I pushed them into a block with precision reamed holes, in .005" increments, 4 steps.
I didn't measure the primer pocket of flash hole as I intend to use a 27 cal power cartridge and shoot these as a RF.
Of course this could have been done for center fire primer with a different mandrel on my arbor press.
I pressed them into each hole till the rim bottomed out, then pushed them out with a bolt.
I don't think Bibbyman is going to have any issues other than fouling with the Black Powder.
Curious if he has any Black MZ left to try in it.
