Ok so,
tommorow I am going out in my shop to my trusty lathe to turn out a new powder thu expander die for my 350 legend.
My Lee 200 gr gc bullets are sized .356 thru my new to me star luber. Finially found 4 at a gun show last year, and bought a pair. Makes lubing/sizing kinda fun for me.
Any how I need a dillon style powder thu expander , trying to be thrifty and use my shop stuff, I want to turn one out.
The lyman M die dimensions I have are .3528 on the initial diameter that goes in the case neck.
the 2nd diameter is .3577 I'll call it for the M step.
Any opinions on what adjustments I might make in diameter? Let's call the small diameter A and the 2nd one B.
And what kind of length would you put on dim A and B, so I don't cut it too short?
Then I need a 9mm one also, same dimensions again except oal?
Thank you for your support
