During deer season 2004 (or so)
My Dad and I were out at one of our friend's farm in Halfway, MO. After the morning hunt, all of the hunters in our party (about 6-7 guys, mostly middle aged men) met back at the house for some lunch and to talk about what we had seen. The house is right by the main road in, which looks over a huge pasture spanning over 180 degrees of mostly flat grasslands with only rows of trees in the distance for any reference. We were all chatting and having coffee outside just basking in the sun and telling jokes when my Dad's friend, the owner of the house, noticed a row of turkeys wayyy out walking right in front of a row of trees in the distance. With the naked eye, even with perfect vision, I could just BARELY make out movement. A few guys broke out binocs and were taking turns making guesses at the range ... "its gotta be 600 yards" ... "nah, thats only 400 yards" ...or ... "looks like half a mile to me!"
One of the guys had poked fun at me for carrying such a heavy rifle for deer hunting: a Remington 700 VLS in .243 w/ 26" heavy varmint barrel, a high power scope and a bipod (in my hunting pack). I had mentioned that it was the only high powered rifle that I owned and was for varmints AND deer... and that I was accurate with it and knew my range tables. The owner of the house said "Hey, Nick. You've got your turkey tag. I'd bet you can't hit that turkey from here..." (Keep in mind I was only 24 years old at the time and easily the youngest hunter there, surrounded by older adults).
I accepted the challenge and set my rifle with bipod down on the picnic table under the shade of a large tree in his yard. I tried to look for objects around the area of the turkeys that I could use as a reference but there were none, save the turkeys. I figured that the distance was approximately 500-550 yards and figured that my .243 95gr NBT would drop about 75" at that range. There was a slight breeze I took as about 3 mph at an oblique angle. I set up, cranked my scope (B&L Elite 4200 4-16x50mm) up to 16x, picked the last turkey in the row (far left), called my shot "far left turkey!", held over and to the right of his bead what LOOKED to be about six feet and a bit for wind and held for the bird to slow down its gait. I slowly pressed the trigged and felt the recoil as I followed through on the shot.
What happened next was great. The other six seasoned hunters, some of which I had known for only a day or so, applauded in surprise and disbelief. "WHOOOAAA!!! YOU GOT HIM!!" The turkey on the far left flopped around a bit and then was still.
I chucked out my empty brass, pocketed it, got up, retracted the legs of my bipod, turned around and did my best to not act surpised. We later measured the distance at 495 yards.
Great day.
Nothing like showing up your elders with a truly great shot.
