Easy to kill, but unless you hit CNS or a lot of bone, they can take a minute to figure out they are dead.
Yeah but unlike an elk they don’t run very far. I’ve shot em and had em just stand there making you wonder , then you put another one in em and they still just stand there then they sway and go down. I hit one with a 300 WM 3 times all shots in close proximity in vitals, didn’t go 10 ft and then it just fell over. Seen em killed with a lot of different calibers and none really made a whole bunch of difference in how fast they died. From 270 win-375 H&H
