Just got a chance to actually measure and neck down some Nosler brass. The “fully prep ready to load” brass is very consistent. Lengthwise it is within .001. Neck diameter is within .0005. I stopped measuring after 8 pieces. I don’t know where it was made but I don’t honk you can ask for much more. I will shoot some of it along with the regular Nosler and see how it holds up.

Nosler brass does seem to show promise. I got around to loading up some of the Nosler 6.5 Creedmoor brass. It seemed consistent and the primer pockets were very tight. As long as the brass isn't soft it should withstand a number of firings before the primer pockets give up the ghost.
