Anyone used these? If so on what, and how did they penetrate?

I assume you are talking about the 350gr bullets.

I used them on my first safari many years ago and they preformed well on zebra and kudu. The zebra was shot through both shoulders and the kudu was lung shot. Neither bullet was recovered.

Have just shot them as practice bullets ... work well for that. I use 350 gr X and TSX bullets for the real deal. They have performed flawlessly on Gemsbock, Hartebeast, and Cape Buffalo.

Very accurate and inexpensive on paper. When there is dangerous game in the area, I use Swift A Frame with excellent results.
