Youngun,
Great post and good luck with your long range shooting...... one thing for sure, it will keep you out of trouble. After you spend all your money on guns, ammo, and optics you won't have any money to be chasing girls or any of that kind of stuff
I'll give you my two longest.
I shot a doe at 1007 yards several years ago. Here in the hills of Arkansas it is hard to find a place you can see 1000 yards much less shoot that far, but I really wanted to kill something at 1000+. I have a place where I can see that far, and started putting out corn to get deer coming to the spot (it is legal to bait in AR). After a week or so of putting out corn I set up one evening and shot a doe shooting prone from a bipod with a 338 Kahn. I had my 1000+ yard shot but still it was kind of a set up......
Since then I have taken many critters in the 400, 500 and even some in the 700+ range in true hunting / field conditions, but nothing further than about 725 until this fall.
This fall I shot an antelope doe at 940 yards on a hunt out in WY. The best part of that shot was that I had a couple of non-believers watching. They think all this long range stuff is just luck........ Both just about fell over when I killed a bedded down doe the first shot with about 12 mph crosswind to deal with.
Keep shooting and have fun!
