if anyone has some data that can fill some of the gaps in this list please feel free to post so I can get it as detailed as possible, heck maybe we can submit it to Hogdon and get it published.
I've noticed that in most of the manuals I've looked at a lot of the cartridges that have both 4064 and 3031 data call for less 3031 to get the same velocity which is why I am perplexed as to why the 3031 had the hottest loads, hence the addition of a lighter load with an unknown velocity. if anyone is willing and able to test that load with a chrono and give their .02 that would be great.
