Re: 260 pronghorn/coyote bullet
I have shot lots of antelope and mule deer with the 140gr A-Max from my .260AI. They are going 2928 fps. Always worked as they are supposed to. It's a very accurate bullet and forgiving on seating depth. I've also had good long range accuracy with Nosler's 140gr Custom Competition bullet. I've not shot any game with them. I might try it on antelope next month.
There's no bad way to kill a snake.
