yea, but logically after the first round leaves the barrel and the bolt loads the next round, you have barrel lift.... (recoil) so you would need to dampen ALL the recoil of the weapon.
by RAW it works, I am not arguing. But by physics, it doesn't.
guess I'll chalk it up to "only in SR"....
From my (admittedly limited, target range time not military) experience taking the time to properly aquire a target and get a good point of aim before firing is a lot more accurate than just raising the weapon and firing even with an automatic.
you are very right, but the issue at hand is the "climb" of the barrel. as the bullet leaves the barrel, the barrel is "thrown" up as the gasses escape. Also, you have the bolt (receiver, loader.... differs with who you ask), pulling back, ejecting the spent shell, and slamming the new round into place, which causes "jerking" tot he weapon on the whole.
So even if you lined up a perfect shot, then fired a burst: the first round would dead on target (we hope), but the next bullet would not, nor the next or the next or the next..... if you aimed at the belly of the target, you would end up "walking" a spray of bullets from his belly all the way up to and possibly over his head.... (and extreme range would just make the spread of round worse)
but that is RL... and this is in SR. like I said, it fits RAW, so I can not really complain. (well, yes I can, but no one cares

and "good for the goose..." and all that.)
