Going to start loading 9mm now that I bought one for my wife. Does anyone have any advice on particulars. Just got all my brass sorted and I probably have 3500 9mm. Are there any headstamps I should avoid? Any favorites? I keep my Winchester 45 ACP cases separate from the rest because my reloading does perform better and more consistent with it. It almost never fails the case gauge after reloading. Most of the other brass gets a final crimp with a Lee Factory Crimp die.
