I have just started loading. 223 for an AR-15 on my Dillon 550. I ham having alot of trouble with getting the new primer seated in the brass. The primers get jammed going into the pocket and is deforming the primers. I have tried stopping on the downstroke and cleaning the pockets but even this has limited success. The brass is once fired Rem.. 223 and CCI 400 primers. I don't know if this is press issue or brass issue. (the press works 100% for 9mm and .45ACP) Does anyone have any tips or experience with this problem? Thanks
