I use the case deburring tool...milserp .223 and some hornady once fired .308 and .270....think they mustve started crimping the superpreformance stuff and just kept going...a quick whirl sorts it and sure makes seating primers a breaze,its like boattail Vs flat base...there is no check before slipping in...never seen any adverse effects at all..never had one fall out or burst or anything diferent to non deburred.
