My SR10's hop-up has a unique issue. At full hop-up the bb's were not curving upwards, although the protrusions in the barrel moved appropriately. I took the hop-up apart with the aid of the thread on this forum - thanks. I cleaned every part and reinstalled, all the time checking the nubs that protrude into the barrel which always worked correctly. Now the range is a bit better, but I never get the bb to curve upwards and at full hop-up the bb curves downward until I back off the hop-up a bit.
Try swabbing the bucking protrusions with a Q-Tip. If you get any dirt or geese out that my be your problem. Also, I would reinforce the nub by taking a small amount of wire cut to the same length as the nub and placing it inside the hole in the nub. This will make the nub firmer and give you more hop. Many people claim the KWA G2 bucking is weak, it's the nub IMO and I have yet to find one that I couldn't over hop .30 gr BB's with.
