[QUOTE="benchracer, post: 825717, member: 22069"] Base to tip OAL will vary with bullet length and shape. Different bullets will contact the rifling at different lengths. A monometal bullet like the Barnes will be longer for a given weight because copper is less dense than lead. Have you tested for seating depth? Barnes recommends seating their bullets .030 to .70 from the rifling. Now that you know your length to the rifling, back the bullet off and load 3 or 5 shot groups at the following depths: .030, .050, .070 from the rifling. Shoot them in round robin fashion. One of the groups will likely shoot better than the others. Use that seating depth to do your powder charge workup. Fine tune your seating depth, if desired. When you are finished with that process, you should have a load that shoots as well as it is going to with the combination of components you are using. [/QUOTE]
