I took virtually this exact shot with my compound back in 1984-relatively slow bow. The arrow entered quartering in just in front of the shoulder but at time of impact did not appear to penetrate far enough for a good clean kill. When the deer was recovered the arrow was broke off but had penetrated the heart. I believe the deer pushed the arrow far enough for a leathel shot by running it into a tree as he ran off. The buck had an inside spread of 28" plus. All things considered I WOULD NOT take this shot again. At the time I was brand new to archery and did not realize the risk envolved with taking this shot. I don't believe this is an ethical shot even though I was fortunate enough to recover the animal.
