6mm SAUM dies and reamer ?

[hemiford]

I would like to neck down GAP-4s brass to 6mm SAUM. Does anyone make a die set for this round
or is it custom deal ? Same question for a 6-SAUM reamer.

A 6.5 SAUM bushing die can be used to neck down with a 6mm bushing. The reamer is likely a custom deal unless you find a gunsmith who has one.

I use a 7saum redding bushing die with a 6mm bushing. I had my own custom reamer made.
