Mr. Brooks, welcome and to answer your question there are a couple of 17HMR rounds that you can use. Hornady makes a 17 and 20 grain selection and the 20 would be best.
You will catch a lot of grief for using the 17HMR on yotes and cats, but the guys giving grief could not hit the side of a barn and their gun of choice would be the RPG. Now you will notice that there is no skill involved in shooting guns like bazooka's and RPG, it usually requires only a point and pull the trigger.
Yotes are a bit tough at times and therefore your shot selection must be right on the vitals or else don't shoot. As far as bobcats the 17HMR will do just fine but keep your shot distance below 100 yards and you will be just fine.
Now let me sit back and wait for the big guns to tell you that you must use something like a 7mm mag on that Bobcat. Cooper17HMR
