A guy I know was shooting at a mule deer in Wy. He missed the buck he was shooting at and hit a buck he didn’t see.

In SA I was finishing up a plains game hunt with Kudu. Last day we finally get on, at the shot my Dad, driver and tracker slap my back and say good shot. PH says you completely missed, we say no he dropped on his nose. He hurriedly asks do you want 2? Sure! The bigger went 61”, over the years it’s grown to 63” but who’s gonna go measure.

Been there when it happened twice but i wasnt shooting...

Ive done it a few times. When I was goat culling Id wait till two came together for the first shot. usually the front ones head over the shoulder of the second. Best day was 14 for 9 shots.
My brother and Father were hunting pigs one night when two good boars came out. Father joking said to brother, "A good man would get both those with one shot". Brother aims rifle and boom, both drop dead. Turns to dad and winks.

I have shot multiple hogs with one shot many times. I once killed 3 dead on the spot with a 4th wheezing in the swamp.

On my very first safari, I killed 2 zebra with one shot. No one had seen the second zebra.

In 2014, I did a heart/lung on a tuskless. It passed through and hit another elephant . We recovered the second elephant the next day.

Just once. Cousin and myself were hunting ducks along a creek bank. Told him I walk down through the woods and try flushing some ducks back upstream. As soon as I approached the bank about 8 Wood Ducks went up. I fired and saw the drake fall, but swear I saw a hen flutter on the opposite bank. Sure enough I found here lying in the grass. Had the taxidermist mount them and still have it to this day. That was well over 20 years ago.

I killed two elk with one shot last year in Wyoming. Used a 280 ackley and Barnes TTSX bullets. Waited for a cow to present a clear shot at 225 yards. Dropped her cleanly on a steep hill, and she rolled down a good 100 yards towards me. Walked up, notched my tag, and started skinning when a second cow tumbled down the hill and stopped rolling within 10 yards of the first. Talk about surprised!
I recovered the spent TTSX from the second cow under the off side skin. All I can figure is it deflected going through the first elk.
I had two cow tags for the unit, so not a legal problem, but I was hunting solo and about 3 miles back in. It made for a very, very long two days of packing meat.
