Norma 300 saum brass specs

[Cakes]

Working on a 7-300 saum project and as there is no Norma 300 saum brass currently to be found, I am in need of the NIB neck wall thicknesses so I can determine my reamer specs. On a side note I do have a new bag of WW 7wsm brass for trade if someone has some norma brass just lying around looking for a home. Many Thanks, Eric in DL

I'll check, just got 1C from Midway a week ago. ???

I just weight sorted 250 Norma USA in the 25 count boxes. After necking down to 7mm and expanding for the neck turner, the four lightest cases had a maximum wall thickness of 0.0160 inches. Hope this helps.

Tony- Thanks for the info. Looks like new shipments of Norma brass are due out this spring. Is your chamber a turn or no-turn and by chance what are the specs on your chamber if I might ask? Thanks, Eric in DL

My reamer is a PT&G with a 0.313 inch chamber neck. I usually run a 0.310 inch loaded neck with a Berger 180 Hybrid. Other than that, I can't tell you very much. I sent Dave Kiff a dummy round with new brass and he did the rest.
