New systems, hardware and methods for extremely precise aiming and shooting of firearms by relatively unskilled users are provided. In some embodiments, shots may be planned in advance and rapidly carried out. A specialized control system comprising computer hardware allows a user to plot a planned shot or shot sequence with indicators on a site display, evaluate the accuracy of the planned shot(s), adjust the location of the shot(s), and then shoot. In some embodiments, the system may counteract and otherwise adjust for certain ballistic and other accuracy-impacting factors with a position-actuable firing mechanism to maintain a projected flight path of such a point of impact at all times. The system is unobtrusive, allowing users to engage ordinary targeting activity, including ordinary firearm aiming movements. In some embodiments, aiming and execution aspects of the invention are adapted to non-lethal measures, which may be assigned by the system autonomously.
