460 Weatherby does surprisingly little damage. Small hole in and out but coyotes have never taken a step after being hit. We used to shoot them LD with 300 Win and 147 grain BT FMJs. 800-1000 yards they are good on pelts and the yotes don't go anywhere 95% of the time. Odd one would run a short ways when heart shot. If you shot them under 150 yards with the 300 win, not at all fur friendly even with the solid bullet.
If you have pics of the kill it would be pretty neat to see. I have not seen any kills on this forum with the .460 Weatherby.
