I'm wary of any rattler until it's head's been severed and buried. Once, on a hunting trip, I found a den with a huge Western Diamondback, partially exposed, and fished it out with my snake hook, pinned its head with my hook, and was about to sever the head, when a new guy to our party, a short, slightly built Aussie dentist, Harvey, insisted that he wanted the snake, entire, as a taxidermy trophy. I advised against it, but he was insistent so I turned the balance of the capture operation over to him.
He seized the snake by what I guess you'd call its "neck" (snakes have more neck than giraffes...), and had to hold it head high to keep from dragging the rattles on the ground. He, along with the two other members of our party, proceeded toward our camp, down a steep slope covered with ball-bearing-like loose, decomposed granite. Harvey was somewhat off balance, with the snake held high, and away from his face. The trio advanced, close together, but I held back some distance. At some point, one of them, realizing that I was not keeping pace, turned around and asked if something was wrong.
"Not yet," I replied, " but we're on a mighty slippery slope, and while I don't think Harvey's very smart to be carrying a live rattler down this slope by hand, I'm pretty sure that he's smart enough to fling that snake as far away from himself as he can, if he loses his footing. I'm just staying out of range..."
