300 Rummy, My only concern with your concept is the velocity factor. Anytime stricking velocity is over 3000 fps, Barnes X bullets can shed their petals from the violent expansion. You will still have the majority of the bullet, but the nose "cutting" petals will be gone and one large blunt will be present. At "long range", your velocity will bleed off to be under 3000 fps, but be aware of the petal loss if contact is too close. Just a thought. :
