I lean towards the story being stretched a bit, maybe he didn't fire 8 shots, and it may have been the ammo, or the operator. With any factor I will share my story.
Embarrassing story to me, but many years ago I went deer hunting with my Uncle for the first time, I carried a single shot 10ga, he carried the 12ga pump. I shot both of them before, target practicing, I had no problems handling either one.
As the story goes, he takes me to my tree, I clear the leaves and twigs away and stand next to it. He points out the trails and tells me to watch the hilltop, that's where they wil come from. He moves off through the woods and sets up. No more then 15 mins goes by and sure enough here comes the deer. I wait for them to move in closer, one breaks off from the group and comes to withen 10 yards of me.
Raised and ready, nose running from the cold, trying not to make a noise, shaking ,thinking, remembering, and contimplating my first kill, I finally take sight and fire.
Nothing, the deer didn't move, other then raising it's head, as quickly as I could I grabbed another slug and reloaded, the deer takes a few steps and again, aim, breathe, aim, fire.
The deer jumps and moves a few yards. I thought to myself, did I hit it? No, maybe not, again I decide to reload, by now I'm fumbling to get another shell out and into the gun, I drop it on the ground, all the time the deer just looking around, and starts walking back up the trail.
Finally reloaded, I wait for the deer to turn just a bit and sure enough I get another perfect chance, one final shot and....
The deer takes off after the third shot, I sit tight for a few and start looking for fur, blood, anything. My Uncle meets up with me and I tell him the story, of course he laughs, 3 shots with a single shot shotgun and all were a miss. He told me I proabably could of clubbed the thing to death eaiser.
What can I say, it was my first time, she gave me three perfect broadside shots, and I blew it.
Maybe the deer was deaf, obviously blind to the boy in the bright orange vest with a shotgun, reloading time after time.
But it will be a time I will never forget, my Uncle passed away last year and we had some great times shooting, hunting, fishing, and the all the stories, jokes, and laughs that go with them.
