I have seen it done several different ways and was wondering if there are any one or more ways to properly mark a bullet group on a target?
I have seen some people mark the target by outside edge of the farthest bullets from the group then sub-track one caliber diameter bullet that was shot.
I've also seen people measure the bullet's center's hole of the two farthest bullets.
The edge? The grey mark of the bullet left on paper or the actual hole cut edge made by the bullet?
OR?
