Discussing how to modify a 40S&W into a 8mm nambu using a 32 Win Spl and some readily available dies.
Using a standard 32spl sizing die to form/size 8mm Nambu..
Here's some dimensions:
____________Ref.________Resized_________Fired
Neck..........(.343").............(.344")................(.345")
Shoulder....(.394").............(.399")................(.403")
Base...........(.403")............(.405")................(.406")
Rim.............(.413")............(.408")................(.408")
Case Ht......(.844").............(.840")...............(.834")#
Shldr Ht......(.604"):............(.598")...............(.650")##
(#) A bit misleading
(##) I've seen others make this same observation - I think it's "normal" for this cartridge. Could be addressed if need be.
BTW RCBS also has another mold 082023 which could also be modified to work as its .310"X120gr. There may be others. My choice was driven by what I could find cheap.
