I went to a 6.5 Grendel AR for this reason. I have shot a few coyotes with a 55 Gr. ballistic tip and had them run off a ways. The problem with coyote hunting
is that you don't get that good set shot that you are always looking for. Sometimes those yotes seem to have a way of making you have to make an uncomfortable or hard shot. They seem to come into the place that you don't want them too. I shoot a 120 gr ballistic tip out of my Grendel and no matter where I hit them, they do not run far even if it is bad shot placement.
The 55 gr ballistic tip will do great if you hit them right which is what it comes down to. I don't care about pelts so I don't care about all the carnage it makes.
