Speaking on this topic IIRC P.O.Ackley thought that the .226 Barnes QT with 125 gr.bullet very deadly on big game animals at extreme ranges because of it's high sustained velocity and tough constructed Barnes bullet. 125gr. vel. 2700fps,twist 5.5" don't if there is any thing here to compare but just mention it.

northcountry that's a pretty heavy bullet for .226 cal!
