That will have to wait until the spring when I can get outside to test at longer ranges....
Actually, looking at the groups, although in the mid 800s they were among the best with each pellet, some of the best groups occurred at 1000 fps and over, and the rest were mostly in the mid 900s.... However a few good groups occurred at other velocities as well.... The differences between pellets were generally larger than the difference between velocities with the same pellet.... All this data looks at is the position of the center of the group, not the size of it.... That will have to wait until the spring when I can get outside to test at longer ranges....Bob
That "tuner" sounds very much like the "Browning Boss" system.
