Jim,
Another variable to add to the list!
As long as the testing is done with 10 rounds that have the same cast bullet with 1 ring filled with Ben's Red, and the next 10 rounds will have 2 rings filled with Ben's Red. All other factors on the 20 rounds being identical.
If there is a marked difference in performance and the above is the only difference in the 2 loads, it will be easy to isolate the best performer.
