I used the partition on a few deer and it just passed right through and the deer ran for 70 or 80 yards.
Yes, it DID pass on through!! BUT, that doesn't mean it didn't expand!!! NP's are designed to blow the nose off, and expand to the partition. Then from the partition back, they drive on through!!
That's the BEST part, they expand easily, yet drive on through for a good exit hole to bleed out of!! Also, they will penetrate deep, or on through, on "rakeing shots" too. HUGE advantage there!
