I wold deffinetly suspect your output psi. Personally I think 260 fps is fine for pump. I always play in close, but I wouldn't want to be much less then that. If you have a barrel kit laying around you may be able to get the velocity up by underboring. Your Ninja should be able to be adjusted to the 800-850 range. It has to be taken apart and have the correct number of washers in place. It should be something your local shop can do easily. I guess I haven't tried mine on the Hammer 7. I just use 12grams. It always worked fine on my other Nelsons ( Phantoms and old Hammer)
