Jim 44-40,
The other advise is correct. I size .0285"+ bullets down to 0.278" (custom made) in the Lee Sizing Dies. I use a couple of juck 280642's (0.278") with Lee Alox on them to lube the inside of the 0.278" die. I then size a few 287346's (0.285") down to 0.278". When it gets difficult to push the oversize slugs through the 0.278" die, I push another lubed one through. I have tried just lubing the inside of the die, but it doesn't seem to work as well. Maybe some type of wax would also work. Good-luck...BCB
