With the yotes, I think it might be hard to compensate for pelt, most Ive seen aren't worth pelting. Having said that, I used the Federal Power-Shok .243 90gr for whitetail in Montana. The entry wound was pinky size at worst and the exit I could hardly get my thumb in. That was at 70-80 yards, low neck entry, high rib exit. Broke neck and a rib or two.
For the yotes, Id look for a low expansion round that won't frag to much. That will help with keeping the pelt nicer.
Bears, Cougs, Deer you have to consider that you want to drop them with that 1st shot, and vital disruption from the impact of the round traveling through the animal is paramount. The round has to do serious damage, can mean the diff. between wounded and dead. I dont think there are to many things more dangerous than a wounded coug or bear in the thick brush. Pelts can be repaired with fur from legs and even other pelts. Ive heard of taxidermists using capes from other deer to make mounts when the original cape is unavailable.
Hope that helps, you can find expansion rates and frag rates on most manufacturers web sites.
