improvised case mouth bell die

[fishman]

Not sure if this is common knowledge or if I came up with a handy trick. In lieu of a 30 cal case mouth bell die, which is needed to load lead bullets, a .357 sizing die can be used. The expander ball, adjusted accordingly, puts a nice consistent bell on 300 blk brass.

A Lee thirty cal rifle die works too.

A Lee thirty cal rifle die works too.

This is what I use, but in fairness, I haven't tried a 357 die.
