I had a housefire last Monday, all of my reloading equipment and components were in the carport. Much of my brass was in factory card board boxes, zip lock bags, and plastic totes. Bullets were in factory boxes. Most of the cardboard boxes aren't burnt and are in near perfect condition. Bullet boxes are intact and not burnt.. any info would be great

First, I hope everyone is okay and this is all you had to worry about.

I will hazard a guess though...brass begins to aneal at 700F (I believe, someone correct me if I am wrong) so if the plastic bags and totes didn't melt I seriously doubt there is any softening or other similar issues affecting your brass and bullets. Likewise with the carboard boxes and such, if they are in good shape and the stickers/ink show no signs of heat then I would rock on.

I will let someone else take a guess about powder if that was in the vacinity. It doesn't take near as much heat to affect the moisture content of powder is would be required to alter the brass/bullets.

I wouldn't worry about any of it being harmed
