This is a tough one for me. There are not a lot of long range shooters in my neck of the woods (Northeast) and a lot of us know each other. The problem with this whole debate is peoples (hunters) perceptions: easy, far, ethical, etc.
Like Pete said, most of the members of this forum can shoot better at 700 yds than the majority of shooters can at 100 yds. The problem is, the plethora of long range TV shows, videos, magazine articles, and computer chat make anyone think they can do it, which they can if they put in the time, effort, and money to do it. But do they?
From what I have seen at public ranges is most hunters (around here) don't. And in most (if not all) of the hunting camps I have shared with guides, they don't either. What upsets me immensely is other hunters watching the videos, reading the articles, and thinking they can do it too. But, they are not putting in the most valuable part: time and practice.
I took my son (13) to Montana last year on a guided elk hunt (could not take him out of school for long enough for DIY). 7 hunters in camp including us. Many topics came up after evening meal. One night, it was how far can you shoot? One hunter, really nice guy (dentist) said he was good to 500 yds. Had a nice Tikka with Swarovski Z5 with the BDC turret. He said he was dialed in to 500 yds. Never shot past 100 yds, but he sent his info to Swarovski and they made him a custom turret. I asked to see his rifle later in the week (i was interested in scope) the scope was so canted I could not believe it. Another gentleman had another Tikka (300wsm) with Nikon scope with their BDC reticle. Same story. He bought the gun, bought 3 boxes of ammo (commented how expensive ammo was) shot 2 boxes to practice, and brought the third box to camp to hunt. 40 practice shots. That's it. He knew the drop of his bullets because he looked it up on the Nikon website. He was ready for 500 yds too. These were two nice guys. I'm quite sure they thought they were doing everything ethical. Meanwhile, my son and I sent hundreds of rounds downrange from 450 (him) to 1000 yds (me) from field conditions. Who is right? Who is wrong?
Personally (which is what all of this is about) I want to extend MY ETHICAL range as far as I can. To that end, I have invested significant amount of time and money on equipment and practice to do that. That being said, I want to close the distance as much as I can to ensure precise shot placement.
Several years ago I read a post on this site from a gentleman in Wyoming. He had taken a nice antelope at 1250 yds +/- if remember correctly. He wrote of how he found the buck, got to within 700 +/- yds, then went back to a hill where he was now 1250+/- yds so that he could make his longest kill shot, to which he did. To be honest, I was a little disappointed. I am pleased for the hunter that he made such a long shot and he tagged a nice animal, but why add 500+/- yds to your shot? The way I look at it, there is so much more that can go wrong adding that extra 500 yds, the animal could possibly be wounded. To him though, I'm sure his actions were perfectly ethical.
As far as long range hunting, I don't encourage it or discourage it. I will continue to stretch my effective range, continue to read here and learn from the experts, and continue to take shots at live game at distances and conditions where I am confident in 100% shot placement, after I get as close as I can
. To each his own.
