I have had this happen too. Hornady one shot will not affect your primers. Put all the cases in a tray and spray so the angle is right and get some inside the necks. Wait a minute for it to dry and then load. Might not do any favors for your SD,s but al least it will save your brass. Load some plain bullets. Say some 150 sierra,s with a powder that will get you up to pressure. Once shot and then sized again your shoulders should be tough enough this problem should go away.
