JJP161 Posted August 31, 2015 Share Posted August 31, 2015 First let me say if this has been answered before I do apologize but I could not find the answer. With that said I have Dillon 550B and I am using a Dillon pistol die set in .40 S&W and thesizing/depriming die is giving me issues. If I am loading .40 S&W and the brass is deprimed then I have no issues. But if the brass is not deprimed for the most part it will not deprime the spent primer. If there are no other cases then it will most of the time but if I am loading and the stations are full it will not deprime at least 70% of the time. The brass is a mix of blazer, Winchester and Remington and has been loaded anywhere from 1-5 times. All of my brass is tumbled and about half wet tumbled. I use Hornady One Shot to lubricate my cases before loading. I have replaced the decapping pin with a new one and the problem continues. I have also readjusted the sizing/decapping die with all stations full and the problem continues. Any help would be greatly appreciated. Thank-you very much.
