A friend asked me today if I would come to his property and help him with his coyote problem. I have never been successful hunting them before but he is claiming that he is polluted with them. My question is about caliber. A guy told me today that he has had more than one shot with 223 run away. Should I use 308 instead? I know that this debate wages on but I’m truly curious. I have both and want to use the right thing. Please let me know what your thoughts and experiences are.
