Last week I finally got around to slugging my 1894 44 Cowboy Limited. It's big - almost .433. I have some cast bullets labeled as .431 that are actually .432 so I started making some test loads with them. Unfortunately they are too big for my Lee seating die. They jam on the crimping shoulder, get pushed down into the brass and sometime get pulled back out.

My .431 bullets pass through the die body with no problem but the .432s won't, so they are just a tad to big. I can re-adjust the die and crimp as a separate step but in the long term I want to seat and roll crimp in one step. Also the FCD die that came with the set post sizes the bullet back down to .431 which sorta defeats the purpose of using the .432.

Apparently it's not an uncommon problem and I have read a number of posts where people have used different brand dies that work with no problem. Redding, RCBS and the RCBS Cowboy dies were mentioned. Can anyone confirm what die will work with .432 diameter cast bullets?



Thanks

I use .433/.434 bullets in our Marlin 44mag, it takes those big bullets to fill the throat. I use Lee dies, that have a home made seating plug to deal with the wide flat meplats. I also use a Lyman "M" die on my cases after a full resizing, the "M" die seems to open the cases up deeper, letting the bigger bullets seat better. Then I use a modified ( I shortened the collet for 44mag case length) 44-40 Lee Factory Crimp Die, to crimp the bullet, I know it's a PITA, but, when it's all done I get great accuracy out of a normal inaccurate gun.

Starrbow, thanks. When the .432s are gone I am going to get some .433s because that is what it really needs. Your method will get me going . If a regular 44 die can't handle a .432 then I am pretty sure a .433 will present some challenges.

I load .432s in my 77/44 and the 3 Ruger revolvers I have using RCBS dies, with no problem. The 77/44 Bullet is a WFN and the revolvers use a 300 grain Beartooth LCMN GC.

I use a separate crimp die, a Lee FCD, and had to knock the carbide sizer ring out to maintain bullet size.

Vic, I just got an e-mail back from RCBS. They said their 44 seater will work fine with .432. Thanks for the confirmation. I am off to the MidwayUSA site to order one.
