Bobcats love bird calls, they just can not stand it. Trick is to get close enough to them where they will come. You may loose one now and again with a 22 mag and I used Winchester 40g HP, hits have to be placed in the lungs. If you hit them in the stomach with a 22 mag, they may get away from you.
Shot gun with #4 buck, BB, and lead #2's are very, very effective.
I used a 17 Remington with 25g HP and 17 Mach 4 with 25's to save hides which were worth $450 back in the day.
