Anything that you use for coyotes will work for a bobcat, the only cat I have ever shot was with superformance sst 140gr out of a .270, I do not suggest this for lack of pelt damage. And the bobcat that my brother shot and we got stuffed was with a .270 130 gr corelokts and it wasn't to bad on pelt damage. I would probably use my .223 for good range, good power, but not to much pelt damage plus this is what I take dog calling anyways.
