[QUOTE="RockyMtnMT, post: 1918493, member: 7999"] I think part of the problem is the definition of ogive. It is not a specific point on the the nose of the bullet. It is the shape of the nose of the bullet. Comparator tools are nice but also flawed. They are a hole of some size that slides onto a radius. If the dia of a bullet varies by .0002" the tool will register a much larger difference in length than .0002" because it will slide more or less down the ogive of the bullet exponentially to the diff in the actual dia diff from bullet to bullet. Good thread and worth the read. [/QUOTE]
