I coyote can hear a mouse walking under a foot of snow and you think that a coyote can't hear a suppressed rifle. I've shot at more than a couple and have had them keep coming in. If you think hanging another $1000+ dollars on the end of your rifle is going to put more coyotes on the board, fly at it. I've been around a number of rifles with cans on them and I'm not impressed enough to purchase one. If I need quiet, I take the 22 Mag and call them in closer.

After the first shot the rest are just noise.
