This is just my opinion, but I think you are wasting your time messing with Norma Brass.
To begin with, the Norma 6BR brass is as much as .002 smaller at the case head web. Most 30BR framers are sized to fit Lapua Brass, which from the beginning has always been a tad bigger than either Norma or the old Remington.
And, that Norma, especially the older cases, are too soft to handle the pressures that a 30BR likes.
You can make up 50 cases from Lapua and wear out a barrel with them.
I'm sure others will chime in and say "go for it". But I shoot a 30BR a lot, and there is simply no reason, other than saving a hundred dollars, to use anything but Lapua if you are wanting it to reach it's full potential.
