I was working up a new load for my 6.5 Creed using Sierra's (142 HPBT) and H4350. I found a node between 41.0 and 41.3 grains of powder. The average V0 for 41.0 was 2721 and for 41.3, 2730. Group size was 1.14" (5 shots) at 200 yards for the 41.0 load and 1.5" for the 41.3. SD's was 6.52 for the 41.0 and 7.9 for the 41.3.
Anyway, my buds were telling me that I should load up 5 more rounds each at 41.1 and 41.2 and see if there is any difference. My argument is that we are talking 0.2 grains difference within the range of the two loads and that there are so many other variables that it makes no difference. Differing case capacities, bullet weights, ambient factors such as temperature and shooter error will negate the 0.2 charge difference.
