RE: Single pin sights
If you' re pushing 280 FPS, you won' t have to change a thing in most hunting situations out to 30 yards. If you sight in one pin at 20 yards, you might shoot 2 inches low at 30 with the same pin. Depending on other factors, the drop from 20 to 30 could be around 1-3 inches or so, but it won' t be much. Practice a little with the one pin setup, you might like it.
