I have to be honest with you, I believe that the gun shoots the agg. and we are along for the ride.
I've been blessed over the past couple of years to have been lucky enough to shoot a few small aggs. I recently watched my light varmint gun shoot a .1504 through my scope at Holton. I held at the same point of aim for all 25 record shots. The gun was tuned far beyond my personal capabilities and every shot went basically in the same hole. That gun has been my priamry rifle for the past ten years; so the platform is solid. That barrel had well over 3,000 rounds on it, but has been a very solid performer (with six teen aggs. on it to date). The bullets were out of a lot that Lowell Hottenstein had just made up so they were somewhat unproven to that point. (No longer a concern.) And.... it was only the third teen agg. that I had ever shot with N133, after shooting over 30 (in the last ten years) with pull-down 8208. Go figure.
Each successive group in that agg. got a little larger and my gun started to go out of tune on the last group in the morning (it was a .189) as the temperature rose and the humidity dropped. On Sunday afternoon that same gun (and basically same load) shot a .3448 at 200 yards; go figure again. All of the other shooters at that time were going big, too. But, I had the most to loose in that grand. And I only got the gun back on the last group of Sunday afternoon after tuning the entire day at 200 yards.
So... I believe that I have some qualification to answer this question since I have shot over 50,000 rounds in competition; with some of those aggregates small and many more not-so-small. And my answer is to work the heck out of the tuning system, not try and ride a slow horse in the race (in other words, if it doesn't work well, you need to change it), and.. when the gun is working, let it do its job. Other than that, I agree with James in that it is good equipment, favorable conditions and practice. I would again add to that to not overthink it and know when the gun is working and then let it do what it can when it's on. It sure is neat to watch such a gun do what it does best through your own scope.
