How we arrive at a number for ‘bullet recovered average diameter’ :
The average diameter, as we measure it, is the measurement of the farthest distance
across the face of the bullet ... averaged with the shortest distance across the
bullet. This is typically from 'petal tip to petal tip' and the space in-between the
petals, which is usually close to the caliber of the bullet that was shot.
