So I've tried using a heavier BB and it seems to have helped the grouping situation of the shots. But It still drops a bit... I think I'll try an even BB next time.
I'm a little confused with the whole height over bore issue. Like, the physics doesn't make sense to me atm. How is it that the BB will "SEEM" to drop to me when I'm 10ft away then when I'm like 30ft away?
