They’re not giant. Targets are 1-2 MOA, depending on distance and positioning. Typically you’re engaging multiple targets at multiple distances. Most are known distance, but some aren’t, we also shoot moving targets , and shoot “ no dial “ stages where you engage multiple targets using holdover only. It’s a great test of shooter and equipment. A scope that doesn’t track precisely or return to zero every time doesn’t last long. The high end Vortex scopes have passed those tests. Some of the others being praised in this thread have not.
