In addition to shooter error, that kind of variability in POI can also come from almost anything, including wind, MV, parallax, projectile variations, and likely even changes in the phase of the moon. Are there some that can do it? I'm sure there are, but most cannot.
To the OP, great shooting and very impressive! </div></div>
Calling the shot is about where the sight appeared to be as the bullet cleared the barrel. The shot will either be on or off call; and, on or off call, the shooter can use the call to quickly discern the source/s of shooter/target error. <span style="color: #FF0000">Only very inexperienced shooters here would perceive that to call a shot means to recognize bullet placement in a fine unit of measurement from zero displacement condition.</span> Instead, shooters should understand a useful call is one which merely describes where the bullet strike should be as referenced to a hand on a clock.
The value of calling the shot is that it supports shot analysis. For example, a shot called at 3 o'clock and confirmed by a strike at 3 o'clock eliminates wind as a source of error but makes poor trigger control a possible concern. Also, using the same example, the shooter can conclude there is no need to adjust the sights since the shot went where expected. On the other hand, if the shooter called the shot right-in-there, but the strike was at 9 o'clock, the shooter might have reason to adjust the sight or rethink wind counter. At any rate, an experienced shooter can easily call his shots to the decimal target's value in addition to its placement on the clock. </div></div>
This is exactly what I'm saying and it has little to do with the inherent value of calling shots, a practice I carry out for every shot I take. The OP very simply asked whether it was the bullet or him. When two shots out of a group of five differ in POI by under half the minimum precision value expected for that rifle/ammo combination, it is meaningless to imply that calling those shots would have revealed anything about the underlying reason they were higher than the other three because they were well within the expected precision of the OP's setup at that range.
For that group, the OP could have made any calls he wanted, but it is mathematically impossible to state with any degree of certainty whether those two shots were 1" higher than the other three due to shooter error, or something else entirely, regardless of the call. That amount of displacement could have easily been an [almost] imperceptible shooter error, but it could also have been one of a dozen likely other sources of error that had nothing to do with the shooter whatsoever. Calling those shots would not have revealed the underlying source of a deviation that small.
Many here routinely emphasize shooting fundamentals and shot calling is an important aspect of precision marksmanship training. I would not dispute the value of those points in any way. I am simply saying that in this specific case, where the POIs of the two shots in question were well within the precision of the setup used, it would nearly impossible for most, without a great deal of time, money, and effort, to determine the underlying cause.
As I'm writing this, it occurs to me that possibly the OP made a typo and the two shots were 1' high, rather than 1". That would make a lot more sense and if that is the case, then shot calling as you stated would have been revealing as to the probable underlying cause.
