I hear ya , bobcats are still protected here, and the 20 cal only comes out in the flat open country. If i had any heart issues I wouldn't be in my current occupation , dealing with the most dangerous predators on earth. Amen. I like the bears and cats so far, nada on coyotes , but I do respect their uncanny intellect.We love the wild life, I had to shoot a possum that was getting on top of the house a couple of nights ago, sounded like burglars in the attic!
I would suggest you invest in some 40g BIB bullets for your 20 as they penetrate well if your barrel can stabilize them.
Bobcats are as rough or rougher on fawns than coyotes, fish and game told me. Bobcats are easy to call in if they are close. Young bears will respond to the call, would not suggest it if you have any kind of heart issues.
