The gun works fine against big ships like the Rh BS for example. I wouldnt bother trying to hit a bomber or a gb with it. And as for the fight against the Rogue dessie - it was rather hard to aim the main gun and even harder to hit the dessie given the numerous objects flying inbetween us ( debries ) and the fact that it was hiding behind the stationary Destroyer. Only thing I noticed was that the gun was only reaching about 1.5-2k but again I cant be sure because It may have been hitting debris. It worked nicely in the open space battle which occured later that day.
It could, for example, be buffed visually ( add some explosion effects) because for a gun this big it would be normal to produce a bit of "fireworks":)
