tried this on bpcr board but no replies yet. have seen on boards implication that .43 spanish is hard on brass. think most are referring to 11.5x58 which takes .439 bullets. i have 11.5x57 which takes .454. is this as hard on brass? some claim brass splitting as soon as second loading. if this is case, even tho' cost prohibitive at this time, would prob. have to re-barrel or sell. can anyone help me out? thanks, bubba.
