Ok, so here's the reason behind the question. I had the buck at 30 yards, he was getting nervous so i took the slightly quartering toward me shot. The deer didnt drop, i found no blood nor a deer after many hours of searching. Not wanting to admit to myself i missed, My brain told me i hit shoulder. But he crashed away on all fours. Your input has forced me to admit the fact. So, now i need a trigger job, new shooting stick, new gun club, but not a new caliber. Tx for the feedback.
