As a guy who has used cast bullets extensively and has seen more than his share of expanding bullet failures, I have always been more than a little skeptical but have remained open-minded. That said, I believe there is a perfect bullet and that?s the Swift A-frame. They open on smaller thin-skinned game like whitetail and they will bust through the shoulders of Cape buffalo. A bullet that can do that is pretty much perfect in my estimation. Yeah, they cost more, but there?s no free ride. And XTPs are, well, XTPs...
