I had some brass I had washed in the kitchen oven at 150F to dry. My wife turned it up to preheat to cook the chicken. When I pulled it out the thermometer was at 325F.

Are the cases OK to use or have the case heads lost temper?

I think you're fine.

Google annealing brass like I did not too long ago. There are at least a couple of sites with good reads that will tell you at what temperature brass starts to soften and I think it's significantly higher than 325 degrees F.

From the site on annealing it says below 482-495 you should be fine

Brass is an excellent conductor of heat. A flame applied at any point on a case for a short time will cause the rest of the case to heat very quickly. 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 for a quick answer, I did the Google but did not hit that site.
Sounds like it is good. And it is definitely dry.
Chicken Parm was good too.

Thanks for the link, that is pretty much all there is on the subject.

You've already figured out your cases are fine; I hope the Chicken was tasty.

did you fill the cases with dressing for thanksgiving?

I don't know how much you like dressing Butch, but for me it would take a 155m/m artillery shell casing to be enough for Thanksgiving.

While I'm at it, I'll cease being a wise-ass for a moment and wish you all a Happy Thanksgiving.

The real question was did you say anything to your wife or were you smart and keep your trap shut?

I have learned many things in life and sometimes I use that information appropriately.
This time I said "Oh S###, you turned up the heat!" then I shut up.

If my wife messed with my oven , she wouldn't see me for 3 or 4 days !

If I messed with my wife’s oven I would not want to see her for 2 or 3 days.

I've cooked a couple of batches of brass ( best so far about $400 dollars worth of Norma brass) and it's been fine.

Shoot a couple of reduced loads in some first to re-assure yourself and then forget about it.
