Well.... I guess mine was when I took down a deer with my (obviously oversized) Remington Ultra Mag without putting a hole through the Deer!
Probably 15 years ago... last day of Rifle.... I can only hunt till 10am... got to go to work.... at around 9:30 I spot some doe down below a cliff. I tell my friend to climb down around and walk to them to push them out. I sit where they should come out at end of Ridge. Sure enough they come out.... Fast..... I whistle and some stop... we later measured about 130 yards. I put the Rifle up... look through the Scope and two deer each face the other way are in the scope... I'm pretty sure I can get the one in the neck area..... I shoot!
The Deer Drops immediately! Yes!!! My friend and I walk over and see fur.... wait... a Tail! Seems my shot hit the Tail of the one in front, ricocheted and hit the one behind in the top of the head blowing off a small patch of fur on it's skull.... no hole tho! Killed it will a Concussion to the head!
