Thanks all for your great info. Like I said in my original post, I am very new to reloading, so much so that I havnt even done it and am researching it as I go. I was at a loss for info and regards to if you actually did trim 9mm brass. It wasnt a case of me actually wanting to do it, I was REALLY hoping that the lack of info was because you DIDNT have to trim. It seems my prayers have been answered.

Thanks all for the tips.
