I am just getting into reloading and have a couple of questions concerning lead bullets for 9mm. I have read through this site and it seems to be O.K. to shoot lead out of my M&P, correct? What about a glock? I seem to remember reading sometime back that you should not shoot lead out of a glock. I may be remembering wrong though. And lastly, I am having a hard time locating load data for lead bullets. Is it correct, as a rule of thumb to reduce FMJ load data by 10% when using lead? Thanks for the help.
