I didn't know you can make a sizing die from a chambering reamer. I always thought they made die reamers for that purpose. Do you not need smaller dimensions in a few key areas to resize the brass?
I don't shoot hot loads. I've only ever used chamering reamers for the dies that I've made. And, they primarily neck size only. Everything has worked fine.

Now, if you're talking about hot loads and magnums, then yes, you're probably correct.

Progress. My 2x 1050's are finally bolted down on their new bench. New variable speed case feeder is swapped onto the left 5.56 press. The 2nd variable speed case feeder will be here tomorrow to swap out on the right 9mm press.

It's always a good day when you get an Inline Fabrication delivery.

Just gotta finish the wall behind the bench and mount the Inline Fab rails so I can get all the parts, plates, toolheads, etc. up off the bench and on the wall. Then it will be time to start cranking out 9mm.
