Rule3 said:That seeing the change of color is different than seeing a white hole in the black bullseye on a paper target. Using a grid target on white paper you do not see the hole and make no corrections if it is off??
Or you are just shooting at a target and then go down range and see if you hit it.
The game here is shooting for small groups, not for an actual score. Small groups are a measure of good and consistent execution.
When shooting groups, then, you're not interested in making adjustments during a string of fire. You're establishing a good sight picture for each shot, which includes the target, but physical focus remains on the front sight and mental focus on executing the shot well. Peeking at the target takes your focus away from these, so the point here is no matter what target you use, it's best not to look at the target between shots during a string. ShootNCs just scream at you to peek. Whichever target you use, look at it after your string is completed. And it should simply confirm what you already know.
When shooting for an actual score, though, you don't have the luxury of shooting a full group before making adjustments. You need to adjust after a single hit, which is why it's important to be able to call your shot: If it lands an inch left, you must absolutely know that's where your true POA was when you cleanly broke the shot. Otherwise, you'll just be chasing shots, and your score will suffer. This is one reason why formal target competition isn't the same as shooting groups.
