There’s a huge difference between range and reality. The vast majority of combat casualties for infantry happen within 80 yards, which is why virtually all “assault” or battle rifles are zeroed at a hundred yards.
The vast majority of “skilled” shooters lack access to ranges that have anything over 50 yards available, let alone 100 yards. If you can reliably group 3 inches at 200 yards your probably in the top percentile of marksman in the country. Not many people hunt anymore, and most people going to shooting ranges are going for handguns or rifles zeroed at 100 yards or less.
It probably sounds strange for people who live in communities that hunt or have an avid rifle culture, but not much of the population can even safely handle a rifle anymore, let alone be accurate with one at 200 yards.
Nah, you pretty much always aim for center mass. With modern rounds you’re just as likely to get a clean kill shot with center mass as you are with a head shot. Unless someone is obviously wearing a heavy plate carrier anything faster/heavier than a .223 is going to do the trick.
It’s not like shooting at the range, even at 200 yards hunting deer, your nerves wreck accuracy. I can consistently group 2.5" at 200-300 yards at the range, but that doesn’t transfer over even to hunting deer on family property. Most people haven’t ever shot at a living animal, it makes a difference.
