Was it the brass prep, bullet or die.
Everytime I have measured it inline die wins everytime.
Look at the people who are successful at there discipline there is a reason they do what they do I can guarantee you they have tested many times.
There is no way you can start a bullet in a Redding, RCBS seating die into the neck as straight as a wilson by dropping the bullet down through the stem.
I every bullet set on top of a case before it is seated in a c" conventional die is crooked no matter how good your chamfer is
