What's the point of the exercise? If it is to verify zero on a rifle, as before hunting season or some competition, that's one thing. If it's just to develop a good, tight-shooting load, then it is unnecessary and even counter-productive (in that you're wasting some of those development rounds just to chase the center of the target).
I've seen letters to the editor of magazines complaining that the groups shown were never centered on target, so were meaningless. Certainly not true if making comparative groups is your aim. It's also possible for point of impact to wander as the weather or the barrel heats up. For checking on that, you can't be adjusting the sights to center after every group or you'll lose the very info you're looking for! Doesn't seem odd at all to me. Stu |

For reference, the above message is a reply to a message where: It just struck me as odd that you almost never see it done. Getting a tight group is the hardest part and requires the greatest amount of skill but moving the group to the center of your point of aim can arguably be lots more important... |
