Classic!
When i was young we (family) would go hunting for rattlers on a friend's ranch. That's the only way to "play" with them (rattler at business end of the rifle!).
Or just keep a sharp shovel on hand. Two years ago we had a mariachi band at an event here at the Maynard Dixon ranch in Southern Utah. They were changing clothes in the bunkhouse when suddenly there appeared a large rattler on the back porch. You can imagine their excitement. Our caretaker simply and calmly picked up a shovel and in one quick chop, the rattler was in two pieces. Within fifteen minutes a large hawk swooped down and had dinner.
Oh the joys of living in the high desert.
Rifle, huh?
Either you're a very good shot or extremely sporting.
Back when I was a kid, we used to use modified 410s.
