QB,
This is not suprising. COAL is a good measure, however the distance from the casehead to the ogive of the bullet where it makes contact with the rifling is what truly determines accuracy. If you look at a selection of SMK they will all by slightly different length due to the way the hp tip is formed, however sierra goes to great pains to make the ogive the same shape. Several companies make ogive comparators so that you can truly measure the distance of the ogive-to-casehead dimmensions. They just slip over the point of the bullet. Most match grade bullet seaters do not seat by the nose of the bullet but by the ogive and thats why you'll see slightly different COAL for the same seating depths.
