I shot a nice doe in the jawwith a 1oz slug and it was NOT pretty. I am just grateful I got another one into her before she could run off. I have enough trouble putting one thru the lungs in a real world situation so I need the biggest target I can find. I am not sure why you would want to hit one in the head? Anything I have ever hit in the lungs did not go far and left a fine frothy trail. A head shot is for a rookie or someone who has forgot the value of agood clean respectable kill.>>>>>>>>>>>W hack!!!
