I'm having a barrel chambered in 30 Nos and it looks like the saami reamers are .346.
I'm using Peterson brass (bought a ton of it for a deal) and loaded neck diameter is only .340
Neck thickness is .016 so pretty standard
So with .006 neck expansion plus .002 neck tension when sizing, I'll be working the necks .008 every firing.
Is this gonna give me neck splitting issues?
I've never had a chamber with more than .004 neck clearance
