Why is most commercial 9mm luger ammo avail. only as FMJ. I have been told that this is harder on the barrel than straight lead. I am having a hard time finding straight lead 9mm. Is this a problem or nothing to worry about for punching holes in paper indoors. By FMJ I mean the copper jacket stuff in 115/124/147gr.Win., Amer. Eagle, Etc., and since I have not fired any yet through my CZ85 I have no idea what their going to be like.
