I'd say you are 100% correct in that small groups trump high velocities.
However, I have read some posts where the poster said that they found the best groups to be at load levels below the max listed.
Not doubting their word, as I wasn't there. However, for me that has not been the rule.
Not all of the time of course, but it seems most often that my best groups show up, at or near the max published loading.
I have however, seen during a test series where the groups grew progressively smaller and then suddenly reversed and began to increase in size.
Guess that is what handloading is all about when compaired to just reloading.
Sounds to me like Wyoreman is getting a handle on it for sure!
Keep em coming!
