WE’RE NOT TALKING SUB-MOA ACCURACY HERE: Rifle Accuracy for Home Defense. “For example, the oft- referenced minute of angle (MOA) equals 1.0472 inches at 100 yards. At 50 feet, 1 MOA is just .17 inches. Therefore, even if you have a rack-grade 2-MOA or (gasp) 3-MOA gun, your potential “group” capability at this longer-than-normal distance is going to be .34 to .51 inch, respectively. Unless your house is being swarmed by armed micro drones, there’s a pretty solid chance that a half-inch variance in shot placement is going to get the job done.”
