Where did I miss the question of what rifle was the cartridge fired in?
You will soon learn, I expect, that even brass sized with a small base die is so large, that it won't reduce to fit a gauge. There are chambers out there, so large, that the brass coming out of them cannot be reduced with standard reloading equipment. And that can be a bummer. However, the market has adapted, and the solutions are roll sizers:

At some level of ballooning, industrial level equipment has to be used to swag the cases down to minimum dimensions. And the stuff ain't cheap. Which is another reason no one talks about this stuff.
