Thread: Trying to Wrap my head around it.

What @timattalon has said is the old rule of 3 or "maximum points blank range" from back when people didn't have rangefinders and scopes weren't all twiddly dials. You set your scope so at 100 yards it shot 3 inches high. By the time it's come back to zero it will be very close to 200 yards and when it's dropped 3 inches the range will be 250. So Anywhere between 25 and 250 yards just aim dead on at your game and the bullet should be within 3 inches of that point which for practical hunting is plenty.
