458 Winchester Mag & Lee 2-Cavity Bullet Mold 459-500-3R 45-70 Government

[300leonidas]

Hello! I'm wondering if anyone has used the Lee 2-Cavity Bullet Mold 459-500-3R 45-70 Government in a .458 Win Mag?

I understand there are some unique throat conditions in a 458 Win mag compared to a 45-70 and would like to know if anyone has has success with that bullet design in a 458 win mag?

Thanks!
