IT can't be used at long range so sniping is out. It misses almost half the time regardless of percentage and even at point blank range you don't always get a kill shot.
I tried using it for sniping at range and after it missed 7 times in a row I gave up and one shot killed my target manually. 9 out of 10 times it misses a shot. As for limbs don't even go there.
I can snipe targets all day long without vats and hit head shots and limbs everytime with a scope. So what use it vats?
I use it for spotting only now but other than that I haven't found a use for it. Is this the same for everyone else?
