I am using a Redding body die for 280 A.I.
Fired cases (Nosler 280 A.I. brass)measure 2.140-2.1405 at the datum line.
Fired cases measure .453 at the body shoulder junction.
In trying to set the die for .001-.002 shoulder bump I get a burr at the body shoulder junction completely around the case. The best I can measure the body shoulder junction it is now .450. I use a Lee Collet die for .280 Rem. This burr appears whether I neck size first or body size first.
I am not sure which way to go next.
