First deprime cases in universal decapping die. Then take your sizer die, run the decapping stem all the way up, then turn it back down 2-3 full turns and size your cases. When seating bullets I put a empty case in press run the case into seating die, I turn the die down until it makes contact on the case mouth. Then back the die a half turn back out. Back the seating stem out and screw it until you get whatever oal you want.. but those simple steps have eliminated any run out issues I have had. Like bsa all my dies are rcbs and hornady oh some Lee dies thrown in there..
