shooter
I was looking for the same thing and got talked into the 17. Since then I've read posts that loved it on coyotes under 100yds and posts that just about called you a criminal if you even tried it.
Haven't had the chance yet, and honestly I bought mine wanting a bobcat round for close in calling and got the same reaction AFTER I bought it of course.
Our cats out here (SoCal) in the local mountains seem to run about 25-30lbs so that should not be a problem. Coyotes do get pretty large in some areas so it is easy to see where some come off so hot against the 17 in those areas. Out here a 35lb coyote is a big one. I've seen a couple that could be over 40 in the 30+ years I've been here.
My Savage 93R17 groups the 20gr just about as good as anything else. About 3/4" at 100. Mine likes the CCI gamepoint and I haven't tried any other 20gr loads yet.
I'm sure under 100yds the 20gr will completely pass through a coyote, even if it went through a shoulder, but how well it would put him on the ground I'm not sure. If the chance comes, I'll go neck shot, knowing that little pill will break his neck. I have shot it through 4" hardwood posts at 80yds and it makes a 17 cal entrance and about a 30 cal exit.
All that said, I'm looking into a 22 mag also, just in case. For places that I call where shots could go over 100, I break out the 223.
Just an FYI, the XTP is a hollow point and the Gamepoint is lead filled.
