Anyone cast their own bullets for 50 caliber revolver?

NOE (Night Owl Enterprises) cast bullet forum has a group buy going for a clone version of the LEE 501-440. They need 10 people to commit to the group buy. Already have 5 takers and I?m #5.

NOE 502-458 FN (Lee 440 with PB, GC & HP options). 2 or 4 cavity option

I have many NOE molds. They are top notch.
