(re: PQ2 Gun sighting problem)
I don’t know exactly where you need to hit, but how many times are you turning the screwdriver to adjust the sights? I’ve always had the best luck if I turn it like 10 times, rather than just one or two. I pay more attention to the message (that it’s too high, too low, etc.) than to where the bullets are showing up on the target. By turning that many times based on what the message says, I’m usually able to get it right within a few tries.
