As a newcomer to reloading, I am starting the very basic step of collecting my brass after shooting it at the range. I primarily shoot and plan to only reload 9mm. Is there such a thing as the "best" brass for reloading? Or are they pretty much all the same? I know that American made ammo is generally better than the Russian, Mexican, or other foreign made ones. And so are the brass from the fired cheaper foreign 9mm rounds (such as PPU, Sellier & Bellot, and Tulammo Brass Maxx) still recommended for reloading? One other very basic question: do you use the same brass for the different grain bullets? Or are there different brass recommended for 115, 124, and 147 grain bullets? Thanks in advance for all your answers.
