Ain't never hung a man, but the day ain't over...
Does it have to be deer? I've only ever killed a deer with a truck. My ex got three in one week with my Cadillac though... Do those count? I swear she was trying...
The first time I ever killed a critter, I was 9. It was a dove hunting trip as an early birthday present, opening day of the season, and my birthday was 2 days later (I usually call it a dove "shoot", as I don't even bother with camo or boots).
I carried my red ryder BB gun, and after my dad's buddy saw me clip one on the fly, he handed me his Remmy 870 12 gauge, and said "here, you'll have better luck with this". Luckily, I've always been a big kid. But still, the first bird to fly over while I was using the shotgun, came in from my 12 o'clock, flying straight overhead. I drew a bead, and passed through, giving it a lead. Right when my dad's buddy saw what was about to happen, he yelled "DON'T SHOOT!!" right about the time I pulled the trigger, with the barrel pointing almost straight up.
That gun leveled me. Knocked me flat on my back. I got the bird. But, as I was laying there, flat out, spread eagled, with the shotgun laying on my chest, looking up at my dad and his friend looking down at me, I said "I want one of these", and patted the gun.
I took 5 more that day. 3 of those were one shot, 2 were a miss and I had to pump another round in the chamber and take them on the second shot. I had more in my bag than the two grown men put together (it was a slow field).
I unwrapped a Mossberg 500 12 gauge that Christmas. And I think that's why I have shoulder problems now, from going too big, too young. I saved every penny I could to buy shells, and hit every dove field I could every chance I got, during every season, until I joined the Marines. It made for interesting conversations when a 10 year old boy goes into the bait shop and buys 2 boxes of 6-8 shot, depending on what they have in stock, and never using less than full choke. That was ten years ago that I joined the Marines, and I haven't hit a dove field since. I sold the Mossy a few years ago when the ex put us in a bind and I had to get groceries and gas.
