Thread: Resizing brass vertical marks on neck

Hi all,

I had cleaned all the cases and were also new, but i did ensure they were clean. After i noticed it i did pull the die to bits and its a very nice finish on the inside, no markings or anything.

Being so consistent around the neck it could be the edge between the shoulder and neck being rough?

Im trying to avoid buying new dies due to cost but if thats what it takes ill go down that road,
