Peterson 300 Norma Mag brass

[highdrum]

I have some 300 norma mag Lapua brass I can give you some measurements if your interested?

338NM has less taper than the 300 I do believe.

I was referring to the OP. He is putting up specs for Peterson 300 NM brass.

I went to order some but read that Peterson is going from .580 to .583 above the extractor groove on future runs, which in my case will help some things. What is the measurement in this area of the 300 Norma Mag Lapua brass?

I have 100x peterson undersized brass, 100 Bertram brass, and I just ordered 5 boxes of Berger ammo for my new norma just because I want Lapua brass.
