RE: Recovery, What to do After the Shot.
I've had good results with shoulder hits with my Bear Razorheads. I use an ordinary compound bow, roughly 55 lbs draw weight, carbon arrows. On an adult doe at 16 yards, hit low and quartering slightly in, penetrated less than a foot, but good blood trail, 100 yds, dead. On large buck fawn, broadside < 20 yds, broke the humerus, no blood trail, found dead at 50 yds.
I've seen quite a few shoulder hits with conventional ferrule/insert blade type broadheads, with chisel tip or point, and with those type of broadheads I've never seen a successful result on a shoulder hit. Based on your description of the deer, the penetration, the blood trail, I'd be surprised if you find him. My guess is that he'll survive, maybe long term.
By the way, I don't deliberately aim for the shoulder.My point of aim is dead center through the rib cage.
