I'm a target shooter. I've been shooting high power including 1000 yard matches for over 30 years. I know what conditions, wind, temp, etc. will do to a bullet at 600 or 1000 yards.
We're talking hunting so lets look at a hunting round, for example, an 180 grn 300 WM @ 3000 fps MV.
An one mile an hour wind will move your bullet about 8 inches. No problem, a 1000 yard target has a twenty inch X-10 ring. Look at it this way, a 3 mph wind will move you 24 inches, and 5 mph, 40 inches. How many people can tell the differance between 3 & 5 mph at 1000 yards? The differance between 950 yards and 1000 yards in bullet drop is about 30 inches. How many people are that accurate in range estimation at 1000 yards? How about the temp.? What does it do to your round?
If I'm off a tad on my estimations at a match, I'm gonna drop a point or two, If I'm off a tad while hunting I'm gonna have a gut shot critter that could run for miles before it crawls off to suffer a painful death.
No sir, If I what to shoot long range (and I do), find some targets and range. If I hunt, I'll sight my rifle in for 200 yards and hunt. I've been hunting for over 50 years, killing my first deer at 8 years old, I can count on one hand how many critters I've shot over 100 yards. None over 200 yards.
The only exception I shot a running dog at 237 yards, that wasnt hunting, It was a LE Sniper call out to get the suspected rabid dog to prevent a child from getting an un-necessary series of rabid shots. That was a necessary, not hunting.
I'm also not a fan of shooting running targets even though I've had extensive training and practice.
You wont empress me talking about long range shots on game, even if you make the kill. It tells me you are lucky, not good.
Most impressive hunt I've seen was hunting caribou near King Salmon AK. I set on a hill and watched a guy crawl through the tundra for four hours to get a 30 yards shot with a bow. Now that was hunting.
