I undoubtedly over annealed some brass yesterday. Went to seat bullets and neck was pushed down in to shoulder. Is there any way of hardening the brass and saving these cases?

Brass can only be work hardened. It isn't like steel.Try a couple by heating and allow cooling slow to room temp.
if you cant buy a AMP dont anneal at all. you are bewtter off. the propane one are not good for your brass.
The margin of error is much longer than 2-3 seconds for most cases. I roasted a 3006 brass for a full minute to see what would happen in propane and it was soft but would still keep its form when I seated a bullet. No i did not fire it it was just a dummy round to see if it would work. That's why I want to know how the op managed to get them that soft.No way to save them. In the trash they go.
Use 750 deg Tempilaq if you aren't sure on how long to anneal.
And it's not hard to screw up fellas. Next time you anneal, take a cull case run it up to 750 deg, then leave it in the flame for an extra 2-3 seconds. That's all it takes to destroy the usefulness of the brass by making it way too soft. Everyone who has annealed a lot over the years has done it at some point. If you see the brass glowing red or even a dull red, you screwed up.
You want to see some REALLY touchy brass, try annealing 22 Hornet cases. 1 second too long after temp is reached and you've ruined them.
What's your basis for this claim?
What testing have you personally conducted to prove this?
Or are you just falling for the marketing statements of AMP annealing company?
I have annealed cases by rotating them in flame with various machines for years. As long as I do it correctly so my shoulder bumps and neck tension are consistent after annealing...then guess what? It's working
My annealed cases have a WAY longer useable life than cases that I do not anneal. So I really can't see that there is any truth to your statement.
I ' think you are right about the decimal but Why would some pieces be sized .060 under the majority from factory?I think you have a dancing decimal point.![]()
Heating and cooling is part of the hardning process because brass is not loke steel.Brass can only be work hardened. It isn't like steel.
