Thread: 7x64 forming brass

Sorry, specifically at the shoulder-body junction if I recall correctly from having compared the dimensions of both in the past.

With the neck-shoulder junction getting pushed back, and more taper added, lots of surfaces there where it will matter that the press bottoms out! I'm thinking that in the process of reducing the above dimensions maybe brass gets pushed into the shoulder-body junction to fill this small void. In theory it should be there, so this is something that can only be known by trying it out and inspecting the sized cases. I would be interested to hear if you noticed any sign of this - like a slight accumulation of the sizing wax just around the very outside extremity of the shoulder?
