I shot one deer with the 55 grain hunting load version of that bullet sold as Vortex IIRC. Hit a deer in the front of the neck, as it faced me at about 25 feet and it turned and ran but was down very quickly in a few yards, similar to John Hearne's description. It tore a pretty big wound channel (several inches dia) back through the diaphragm and I never recovered from back in the stomach viscera stuff.

Edited. I missed JHC's post. Thanks for the clarification on rifle round effectiveness.
