I have met Johnny Dury, who owns Dury's Guns in San Antonio along with his brother. His family has a large South Texas property where they hunt. According to him, all the loaner rifles at the ranch are 7mm-08, and that's what he hunts whitetail with also.
For those not familiar, their stores sell somewhere north of 3000 guns a month, and typically has up to 500 for sale online. He could hunt with any caliber and any rifle that he wanted.
I have killed a pile with many calibers. I don't remember a deer we shot with a 7mm-08 that I didn't see it fall.
