Mykey....no, the Partician is NOT designed to lose the foreward section of lead. It' s a failure of the bullet. Interesting however, it' s such a fine bullet that it kills most everything it' s shot at anyway, despite this failure.
Vapodog, I agree with most of what you say, and your knowledge and experience are obvious. But on this one point, I must take issue with you, inless John Nosler lied about how he intended for the Partiton Jacket bullet to work!! I have never heard of an AUTHENTIC CASE of a Nosle Partition Jacket bullet failing! The loss of the front core is NOT A FAILURE!!
