Is This Alpha Brass Just Always Good? Third and Final Powder Tests

Well, I wanted to do a little more testing and see if I could find that super great powder charge. I think all I did was prove that I have a large range that seem to perform really well! Is this Alpha brass just that good? Or am I getting better and my whole setup is giving me excellent results?
I really thought these tests would give me a clear answer on powder weight. Or, at least point out some that I can scratch from the list.

I am sure that now I need to size, mandrel and load up some and see if anything changes after that. I think there is a chance that some numbers will shift around. Hoping with the mandrel die added to my bench that my SD and ES numbers will shrink a little. At the minimum, I hope to get rid of that 1 or 2 every 10 that seem to jump a little outside the range of the majority. I show how some of these necks are not "perfect" out of the new box. I think that may be part of the few higher or lower numbers. Just not sealing and releasing as consistently. The mandrel should solve this issue.
We will see next week!!
I am starting the process this week getting deprimed, annealed and then ready to size over my weekend.

Please let me know what you think!
Is it normal to have like a whole grain range that gives good numbers and groups on target? Or, did I just get lucky here, lol.

Thank you for watching and spending some time here. I hope you have had a great day, and have yourself an awesome weekend!!

This is a private range. All shooting is done in a safe, controlled environment with no people or dwellings within miles to be at risk.
