My son's finally ready to start reloading for his 9mm cause his kid is starting to shoot it as well. So I have been asked to supply components for Christmas. Since I don't reload 9mm myself (yet) I was hoping for some input on choice of powders to use (or not), primers, bullet weight etc. I checked Hodgdons site and see that Universal, Clays, Titegroup, W231, and WSF show up a lot across bullet weights. Any input would be greatly appreciated.
