Re: Ogive caliper attachment
Im not really knowledgable about this so dont quote me on this but I believe that when you find where the lands are, you are finding the length of how long the round must be but from the head of the brass to the OGIVE of the bullet, emphasis on the OGIVE of the bullet (well kind of because you dont want the ogive to exactly touch the lands). When you find what length you want from the head of the brass to ogive of the brass, you measure what that length is, this is where you use the Hornady Bullet Comparator. You do NOT want to measure to the tip of the bullet. Although the length may change when you measure from the head to the tip of the bullet, the ogive should stay the same no matter what. So when you find the length you want from the head to the ogive, you set the seating die to that length (the length to the ogive). I am not sure if all of the seating dies seat by the ogive bullet or seat by the tip of the bullet but usually i think its the ogive. The oal that the book gives you is to the tip of the bullet. You do not want that if you are trying to shoot from a precision bolt action rifle. Now if you want to shoot from a semi auto and with a small magazine, then obviously the length to the tip of the bullet matters. Now im sure if some of this stuff is wrong, someone will chime in and point it out. And by the way, if this is not what you were looking for then im sorry, i must have misunderstood your question.
