Re: 2890 yd elk
The fellows who aspire to that kind of distance have setup a website to share info. Most of the guys here are interested in somewhat less exotic equipment and distances up to 1000 yards or less. We have some very serious shooters who have the equipment and skills to shoot considerably longer, but the vast majority of the guys here are interested in obtaining the confidence to shoot to the lethal accuracy capability of their equipment. Most of our rifles and rigs might be classed as good to 400 or 500 yards, good to 750-800, or good to 1000 and a few guys have the dedication to obtain confidence past 1000. "Good to" means that the bullet can be delivered with lethal accuracy.
Every shot at an animal is a shot at a target that bleeds - whether it is the 75 yard kill I made last week on a Nilgai or the mulie I killed with one shot at 783 yards. If you wish to discuss ethics please do that somewhere else because the fellow who owns the site, and the guys who collaborated on it from day-one only want to share info on improving our personal skills, equipment and enjoyment of hunting. My ethics are mine, and I do not wish to compare or impose them on others. There are extremely long shots made and there are extremely close shots that result in wounding and misses. We are mostly trying to learn more so that individually we can shoot with confidence farther if and when the opportunity happens. You will probably read about more shots inside of 500 yards here than past. But there are a lot of guys who can place their first shot into the lethal zone much farther than the average 200-250 yard shooter.
Your question may well be reasonable from your viewpoint. We have run that stuff around enough in the past to know that nothing is proved and valuable time and energy will be wasted. We are here to talk about equipment, techniques, hunting - including the exploits of ten-year old hunters who have just taken their first hog - important stuff like that.
Let's stay with the topic at hand - long range hunting as the majority of the guys on this site have the skill and equipment to enjoy.
