Did alot of research on this one!!.45 super brass was a hard find..Got the springs for the xd 5inch.The reall kicker is the reloading data;seems there is some sort of clandestine situation.Most data is a "high end" .45acp loading. But alas after alot of snooping found significant data..Even reccomended firearms for use in.Captive chambring is a must,Should have the stuff together shortly,then let the games begin!!I just hope the xd don't throw the brass to the moon. (kinda expensive).Anybody giving this a try should chime in positive or negative,as critisism always an asset!!!Thanks guys!!!
