6mm up from 22cal. Neck Up Mandrel
Necking 220 Russian up to 6mm for forming 6PPC is a pretty easy task, but we've noticed that neck turning mandrel fit can sometimes leave something to be desired. A lot of times the mandrels are tighter than we like or have a strange tight spot even after running the brass through a body die and back over the expanding mandrel. This new mandrel eliminates that problem, as insignificant as it may seem, to give you perfect mandrel fit when using one of our carbide neck turning mandrels.
I wanted to neck up 220 Russian to 6mm for my 6ppc. The long taper with good lube did the job perfectly. Very solid quality.
With a little lube on the expander, it worked perfectly.
