The 17 hmr will do the job out to 150 yards. Not the idea gun for the job. But if thats only thing u got. I wouldn't use a fmj. Hornady 20gr xtp hp ammo. That bullet will get the job done.. I carry a 17 hmr when i am going after bobcats. I use a Hornady 20gr xtp hp. I dont like using a 20 or 22 cal on bobcats.
