I'm with cayugad.

Tracker if you shoot 100 shots at a target at a range the sights zeroed foryou'll find a dense concentration in a ring aroundthe point of aim. They will thin down as the distance from point of aim increases. If you log on a graph the number of shots which miss 0" to 1/2 ", then the number of shots which miss 1/2" to 1", then the number shots which miss 1" to 1.5", and so on, , , then you will get a curve which looks kind of bell like.

Then if you divide each plot point by the number of shot in the sample, you will get a probability curve. Lets say10 shots are 0" to 1/2", 10 divided by 100 is .10 which reflects a 10% probability that any given shot will be within 1/2" of the point of aim.So the probabilityto shoot a sub-MOA one shot group is 10%, a sub MOA two shot group is 1%, a sub MOA 3 shot group is .1 %, a sub MOA 4 shot group is .01% (1 out 10,000 attempts).

Obviously the more concentrated your distribution of probabilities, the more likely it is that you will achieve a sub MOA group. The thing to remember is this, "EVERY SHOT IS A MISS", from the point of aim. This is because the probability of the center of the bullet striking the point of aim is almost ZERO!

Who needs a sub MOA at 100 yard anyway if the game is 100 yards away. Lets say your average group is 4 times worse than that (4 MOA). What does that mean? It means its unlikely to miss your point of aim by more than 2 inches.
