I came across these two older Nosler Partition boxes, both 7mm.
What I learned from Nosler website, is that Nosler moved from Ashland to Bend Oregon in 1958.
Nosler Partition Bullet Co. became Nosler Bullets in 1969.
So I guess these would age to somewhere between 1958-1969.
My question is the "band" around bullets, it's about .002" smaller dia. than surrounding diameter.
Would this be where case neck would be seated and/or crimped? Thats about all I can figure.
You can see where these were lathe turned. Kinda cool.
