My vote also goes for the Noslers Partitions!!
In the several hundred NP's i've shot, in fact probably over a thousand, i've NEVER had the lead come out of the back!!! I'ne never seen it happened for anyone else either! I like them better than any other game bullet i've ever used.
I've taken a lot of deer with .243 Win. with NP's, and they work particulary well in this diameter.
