I don't know exactly what you are getting at here?
For deer hunting I get you're not shooting strings of bullets, so I understand that the first 3 shots are critical. Deer rifles also tend to be pencil profile barrels which are prone to wandering when hot. Hence why so many people are reluctant to shoot larger groups. What I'm saying is that three shots is not enough to see how accurate the rifle is. If you overlayed say two-three three shot groups then you could, with a great deal of confidence, say that your next shot will fall somewhere within the area contained within those previous six-nine shots. However if you just use one three shot group there is quite a high percentage chance your next shot will fall outside the area bounded by your initial three shots. Therefore three shot groups should not be used as a gauge on the accuracy of a rifle and therefore what range it can reliably kill any given game. Also because of the relative ease of producing a small 3 shot group from an inaccurate rifle I would not put much store in somebody touting their rifle is half MOA and showing you a single 3 shot group.
I agree three shot groups do fit a purpose and that purpose is checking a rifle is still zeroed.
