The partition -as great of a bullet it is---is not a bonded type bullet and was not designed to keep a high weight retention compared to todays bullet designs--Per my converstaions with Nosler on previous visits, to the Partition is to maintain approx. 60% of its weight--I would think if you can not find a solid in 30 caliber--a bullet similar in construction to a Barnes would out perform the Partition as to penetration--as the Barnes typically retains 85 to 90% of its weight--especially in lieu of the lower velocities presented by a 30-06 versus a magnum type caliber

This can also be confirmed by bullet comparison tests that I have read-- I have some literature at my home--when I go home this evening I will see if I can find it and report the findings to you..
