Shot a 8 point last fall. Tn deer so maybe 150lbs on the hoof. Not big.

243 with 95nbt. 394 yards. Unfortunately after the shot I found out my gun was shooting 4” to the right meaning I hit too far back. Had just shot it 2 days before to 700 yards and it was dead on. No clue what happened
Slightly quartering away. Bullet hit stomach/liver and exited. Waited 2 hours and then jumped the deer within 80 yards of where I shot him

Went back 2 hours later and he was laying 200 yards away dead. Middle of the day coyotes had already found him and tore up front R shoulder and rear R leg. I don’t let them lay any longer than I have to cause the meat will either spoil or the coyotes will find them

Not saying you made the wrong choice, and congrats to your nephew
Just the way it is when there are coyotes around or the weather is hot
