I admire anyone who can shoot a long way accurately free hand using iron sights. Good for them! Awesome! But there’s a reason people invented scopes and red dots and TrackingPoint-style automated firing systems. To make it easier to hit the damn target. If you’re long way off, use all that stuff and, preferably, a proper sniper rifle. Right tool for the job and all that. And no, I’m not calling myself a tool. That’s your job.
