90% of the ground squirrels I shot are on my permission. The ranch foreman is worried about the cattle breaking their legs by stepping into the holes, so he wants the squirrels gone. As long as I keep thinning the numbers, the foreman is happy. My "job" is to get rid of the squirrels. While head shots are great to see, heart/ling shots are a lot easier and get the job done. I don't want to miss and have the squirrel run down the burrow as it might not come back up while I'm there. Yes, they might still struggle after a heart shot and stumble back to the hole, but he isn't coming back up for breakfast the next day. I might be opening a can of worms, but when I'm at the permission, I'm not worried about ethical kills, I'm just worried about the end result. And yes, a .25 pellet to the chest usually ruins their day
