Yes, I did shoot downhill, I standing on top of the ridge, where there aren't many trees. The squirrel was down the hill aboot 100-150 yards, in the top of a tree. As for specifics of the load, I'm not sure. I'll ask me friend who made it. I know it kicks like everything, it knocked me little brother down when he fired it. And he aint no little thing, either. As far as the pellets in it, it has pellets about the size of .22 cal rifle bullets. Five of them spaced equally around the barrel, and one in the center, only one layer of them. And as for the rifle hitting the target at 250 yards, I don't mean it hit in the circle, it hit exact center.
