I'm trying to determine what reamer specs I need to look for a new barrel in 6mmBR (plain).
I will be using newly manufactured Lapua cases and Berger 105-107-108gr bullets. What would the loaded neck diameter be? I think I want to get a reamer that provides for .003" in total neck clearance. What throat length should I be looking for?
