I have a couple boxes of shells in my " hunting box" that don' t throw a good enough pattern in my setup to kill a turkey every single time at 35 yards. That' s why their in the box and will stay in the box until my next patterning trip
Three pellets in the " kill zone" is not good enough for me because it might put those three in there today but tomorrow with the wind/rain/humidity/Mr. Murphy/little bush/ or God knows what else it might not.
