Ok I am geting ready to start loading 9mm. i am using 125 gr lrn from missourri bullet, and i am using hodgon clays. i have some load data, but i am wanting to expiriment. how do i tell if i am overpressuring the round.I am using the clays, mostly because you dont hav eto use very much, and my uncle has had excellent results. Any advice would be helpfull in working up your own loads.
