It's the exact reason that when i use a premium bullet, it's a Nosler Partition. In the hundreds i've shot, i've yet to have a failure!

I stand by what i keep posting here, NP's have the widest working range of any bullet made! They expand well at low velocities, and drive deep or on through, at high velocity!!!

In all the NP's i've shot at game, i've only recovered two bullets and i have never had one fail to expand!

For me, i'd call your bullet a failure.

BTW, i've seen other bullets do the same thing yours did. (not a TSX)
