HELP!! I cooked my brass

[Vern]

I cleaned my brass last night and I put it in the oven to dry it out.
I only meant for it to get up to 100. But I got side tracked and the temp reached 250 for about 10 - 20 min.

What is the temp where the brass can be damaged.
I know it can come out of the chamber hotter than that so I dont think there is a real issue but some temp facts would make me feel better.
I am suppose to go to the range tomorrow to do some tuning.

A small piece from " The Art & Science of Annealing" article at Accurateshooter.com

There are several temperatures at which brass is affected. Also, the time the brass remains at a given temperature will have an effect. Brass which has been "work hardened" (sometimes referred to as "cold worked") is unaffected by temperatures (Fahrenheit) up to 482 degrees (F) regardless of the time it is left at this temperature. At about 495 degrees (F) some changes in grain structure begins to occur, although the brass remains about as hard as before--it would take a laboratory analysis to see the changes that take place at this temperature.

Thanks Driller, that makes me feel better, I think.
As I understand what is written a temp of 250 for that period of time should not be a problem then.

I really wasnt looking forward to fire forming new brass for the match next week or practice tomorrow.
