I'm betting the exact same load is totally tame... and possibly leaves room for more output charge. Unfortunately it's too hot to venture into the desert this weekend.

OK why is that? Please lets hear your expert knowledge. You need to call any of the powder places an ask them about the cci sr primers. If you have never heard of that then you need to stop loading and rethink what you are doing. And about the annealing you are wrong AGAIN. Federal brass is soft in the head for the reason I said. And how to fix that is easy. This info came from a friend of mine that was the head ballistician at Ruger. I trust what he has said over a wannabe on an internet forum that clearly has no clue.
There are lots of people out there that know stuff you have never heard of before. Sometimes they offer help. But other times people like you drive others away because they think they know it all. I have worked in industrial forging plants for many years and know a little about how to make metals harder or softer and how to make screw ups become usable products.
This will probably be my last helpful insight for you guys.

Notice how the test rifle they (Speer) used in my published data was from a Ruger Mini-14...
Will continue to happily use my CCI 400's in .223 ammo that I make. :)
It' going to be a cool 104 +/- this weekend. So we're good!!
It is a normal thing for primers to flatten with very light loads as the case walls do not stick to the chamber and the case slides backwards while the chamber is still under pressure.
Usually you also see smoky carbon on the case as exhaust gases get between the case and the chamber.
I see it all the time with blooper loads in 7x57 Mausers.
