When you take a rifle and put it in a sled and take 5 shots at a target at 800 yards and all shots are almost touching a shooter will most likely improve his discipline on the shooting technique that he knows so it might help a little on accuracy. If on really wants to improve accuracy learn and practice. Better hunter is very doubtfull. It might actually make some people a worse hunter. I can only wonder how many will think they can hunt out past their skill range and wound animalsBetter hunter?... Yes. More accurate? Possibly ... for two reasons:
#1. Could actually be more precision equipment.
#2. Self confidence and your shooting psyche. Might make the shooter better simply because he THINKS he's better. Unlocks his subconsciously imposed limitation.
