I would suggest that you do the "ladder test" to find out where you are most accurate and least sensitive to loading errors.
This will allow you to find the most accurate load for YOUR exact rifle.
When I did it, using fairly large jumps of 0.5 grains between groups of 2 rounds, I found that the groups broke into three distinct groups.
Below 22 grains Varget behind a 69SMK HPBT, groups were similar.
Between 23 and 24.5, the groups moved up and down, but ALL groups and ALL shots were within a 1 MOA group. At 24.0 Varget, two bullets went in one hole (100 yards). 24.0 was the highest point in the bunch.
Then at 25 grains and above, a new group formed an inch higher.
Therefore, if I loaded to 24 grains Varget, and was slightly off, the shot would move down for either HIGH or LOW loadings -- halving the error likely at any other point. And even a grain high or low would be within a fraction of a MOA. In other words, the shot placement was fairy INsensitive to loading around 24 grains -- in MY rifle.
If you perform the same test in YOUR rifle, you'll likely find a series of loadings where the point of impact is little affected by the change in loading -- those are optimum loadings unless you are a perfect loader.
There may be more to it than that, but that is what I was instructed to do, and it seemed to work.
BTW, from my analysis, Rem Premier Match was much hotter than any of my loads. Took me an hour to make up all the ammo and a hour to shoot it on individual targets, one minute between shots, 2-3 minutes between groups, but the results were astonishing when all plotted on a common x-y axes.
