I have been helping a friend off and on to start reloading . He has been reloading for his .45 cal. 1911 used FMJ round nose bullets but has run out . He has found some Hornady Frontier Lead bullets and asked me if it was ok to use them . I think they are to soft to use but not sure . I remember hearing before about don't use lead bullets in a automatic on revolvers . He sent Hornady a email last week but never got a response back . Anyone got some input on this subject ?
