lee 375 H&H collet die for 375 winchester

[original]

I have tried the 30-30 fire forming and using 38-55 brass for jacket bullets but the case walls seem to be too thin. Will a lee 375 H&H collet die squeeze the upper part of the brass correctly to hold a jacketed bullet?

I ordered the Lee 379-250 die along with a lee 377 sizing die but I just wanted to figure out how to load jacketed until the day someone actually makes 375 win brass again.

Lee Collet neck size die work off of case length.
375 H&H is 2.850
375 win is 2.020

Maybe...just maybe, the H&H die could be modified to work with the win?

You could pull the 375 H&H collet and mandrel out and shorten both to work in a shorter 30-30 collet die body or perhaps another such as a .308W(?). Would lose the deprime function but cases could easily be deprimed with Lee deprime die.

I didn't think about the case length, I will just wait for someone to actually produce new 375wn brass or just forget about loading jacketed bullets. thanks for the info.
