So when you turn the neck down, say .004" less than the chamber, is this dimension before seating a bullet or after seating the bullet? When I seat the bullet the neck expands beyond the full length sized case dimension. I'm guessing that I need to anticipate how much the neck size will change w/ seating and turn the neck accordingly.
Another question, should you turn the neck before necking down to caliber or after necking down?
To hunt... or not to hunt...? What a stupid question.
