[QUOTE="Mikecr, post: 191415, member: 1521"] Great question. It does SEEM like a better idea to get the bullet nose deeper into the seating plug. I think with Secant ogives it would work better, but worse with more common -Tangent ogives. With tangents, contact nearer the tip provides a steeper angle of contact. If your contact were near the nose/bearing junction, there would be such a shallow contact angle that the bullet might wedge into the plug inconsistantly, leaving higher variance in distance to the lands. Well, just a theory. I'm sure it was worked out long ago [/QUOTE]
