Over Annealed Cases?

[Hockaday2017]

I worked up a load for my 6.5 PRC that was amazing. Hornady cases, 57.2 Grains H1000, 147 Grain ELD-M shooting 2970 FPS with under 10 FPS E/S shooting Sub .25 MOA. The thing was an absolute tack driver. I took it out and shot cinder blocks from 850 to just over a thousand yards pretty easily. Then being the kind of person I am and never being satisfied I jumped on the internet and started reading about the annealing process in more depth. I read a number of articles talking about over annealing brass. Everything they said was bad, I was doing. As with everything reloading related, its seems to be 50/50 on what's acceptable and what's not. I changed my annealing process and annealed 50 cases. I loaded 3 of them the exact same way as I have all along and shot them to see the difference. I could immediately tell a difference in the bullet seating force being way more inconstant than it was before. E/S jumped up to over 70 FPS. I have a pretty basic RCBS setup with RCBS Dies. Ive decided to just make an annealer out of a motor and speed controller to get much more repeatable results than the drill and torch. My question is: Is there a way I can harden the brass Ive already annealed so that I can anneal all of it 100% the same way WITHOUT loading and shooting all of them?

Over annealed goes in the trash, you are not going to fix it.

Brass only hardens by work hardening.

I've never annealed a case and never will.

I over annealed about 100 cases with a torch and drill. .005 neck tension and I could push the bullet into the case with a finger. I use a friends amp annealer now.
You could try a neck bushing then expander about a dozen times but I'm tossing mine.

Everything I ever annealed with a drill and torch shot just wonderfully. Yes I over did it a few times. Still never had any trouble with the results though.

I'll never understand spending hundreds of dollars on a machine that does nothing for accuracy, especially on a hunting round level. Annealing is the Starbucks of reloading

For cartridges that I fireform, or cartridges that I put extensive time into brass prep for, or cartridges that I have necked down, I anneal occasionally for the dramatically extended case life. If I was just grabbing a standard 30-06 and doing minimal brass prep.. . Meh, I can just get new brass.
