Just shows how little you know about shooting in general.I guess that shows how little you know about long range hunting/shooting or competitive shooting.
How many ramrods are in these rifles?

I believe all those shooters in those videos know how to shoot a gun and its not in their heads.
Its not going to make any significant difference for the hunter that's only taking shots a game from 25yds to 200yds but, beyond that it can certainly make a difference.
Many things can be left off of guns for convenience not because of accuracy. Lots of folks have left RR out because of noise, tightness, and losing them while shooting and hunting.
You are confusing convenience with accuracy.
