Years back Brian Pearce wrote about a Cape Buffalo hunt with the Marlin 1895 loaded with the old CorBon 405 Penetrator Solid (discontinued) load at 1,650 fps. His chronograph read out at 1700 fps or so for that load. He proceeded to shoot a herd bull and to his surprise it passed through and struck a matriarch cow and passed through her as well. The PH was awestruck at the penetration of a 405 grain bullet at 1700 fps. Does that help?
