Yep.
i watched what a 1000 yard competition was like on one of the outdoor channels that had a segment on it. These guys unload 10 rds or so as fast as they can rack the bolt and pull the trigger. Semi auto fast damn near. The object is to shoot as fast as you can before the wind changes. They get 10 minutes for 10 shots and use all of 8 seconds of them. They arent shooting these world record rifles. They are locked down tight and recoil straight back with no chance of moving from the initial setup. A five year old could do it. This discipline is not about the shooter. It is about the rifle and ammo setup. Gun shoots itself.
Still takes a shooter to watch wind cycle and mirage cycle and know when to shoot. Yeah they shoot fast, like you said, to stay in same conditions. Unlimited is rail guns, br still has light gun and heavy gun. Those heavy gun rifles are about 4-5lbs lighter than prs rigs, lol.
