Had reloaded rounds that wont fit my chamber ( fired from another rifle previously ) after running through my dillon small base 308 dies. This condition persists even after adjusting so that the press cams over into the die. The cases fit a gauge just fine but not in my match chamber. I called Dillon and an older fella suggested I take a few thousandths of an inch off the bottom of the sizer die and try again. I'm not so sure I wanna dick with that. I did buy an RCBS full length size die and it's better but I still get sticky extraction when manually cycling a round. Is the answer to go ahead and file on the die or is this guy full of hot air? Who makes the tightest die set out there so I can size brass fired from sloppy chambers to fit my match chamber? Brass availability is so damned sketchy as it is I really cant just depend on having virgin brass to replace everything that's worn out or lost on the range.
