I lost a big AL pig over the weekend to a shoulder shot. Standing on a slight angle at 140 yds when a 130 Partition from a 270 WSM hit him. I heard the thwack and when I recovered from the shot he was laying on his side not moving. As I was congratulating myself on such a fine job and reaching down to pick up the empty I looked up only to see him dashing off. He was never seen again. No blood. Only three deep prints in the dirt where he jumped back up - the missing print was from the hit shoulder. I was very confident in that shot with that bullet at that speed. He absorbed one heck of a lot of energy. Any thoughts?
