So i shot a doe this afternoon. Hit the front left shoulder and buried about halfway back in the ribs on the right side. Hit heart with it. Heres my question...why didnt it come out the other side? Ive had this happen twice now. One shot was a button buck at 60 yards, and this doe at less than 40. Shooting a smoothbore ithaca with remington sluggers. Not that i needed a pass thru but seems odd at this close of range not to go thru. Retrieved the slug and its almost perfectly flattened out. Thoughts?
