Which short stick powders give you that much variation?
I should clarify that the absolute variation was about 0.5 grains. Plus/minus 0.25
Yesterday I noticed it with RL26 but have noticed it with IMR 7828 short cut. And also H1000 as I recall.
Has anyone tested groups sizes of thrown charges vs. individually weighed charges? And what level of variation starts to become statistically relevant.
