We kill mountain lions with both close up. I used the 17 on a 140 lb male. and it did wel with a good shot placement behind the front shoulder. If you are getting close the 17 will do fine, but if you feel the need the 22 mag will go a little farther. Both are light for the job and shot placement is key.
I know a couple ppl that use a 17hmr but keep shots close with either caliber. Head shots will drop them in most any caliber. I've seen a few shot with a 22mag that died rather quick but shot placement is key, if your shooting for behind the shoulder keep them close I'd say inside 100yd you should be ok. Is there any particular reason you want to go with such a light caliber? On foxes either would work just fine but on big fat yotes like are in my area i want a lil more gun, 223 with 55gn hp work great.
I've lost 3 coyotes with my 17 from 60-140 yards (all chest shots through) and I'm gonna say that bobcats are at least as tough so I'd stay away from it. Unless you shoot the 20 gr FMJ's, which actually act more like a big game bullet. The yotes I've seen shot with the 22 mag died on the spot.
Bobcats are worth some good money, I would hit them with the 17 I think. I've shot a couple in traps with a 17 HMR with zero pelt damage and quick kills, cats kill easy IMO as long as you have a bullet that will open up on them.
