    To put it simply, no. But dont do that to your bow, that answer would be yes.

    If you're worried about a cook-off, it won't get that hot in your car. But I would guess that ammo subjected to a lot of heat should be changed out every few years. I use old ammo for practice and reload with fresh every year.

    WASNT WORRIED ABOUT A COOK-OFF WAS MORE WORRIED ABOUT DETERIORATION OF THE POWDER IN THE ROUNDS UNDER EXTREME TEMPS

    You can do an experiment like I did last year-place one round of ammo in each caliber you want to test on the dashboard of that old Studebaker (you gotta have a Stude, dude)that's rusting away in the backyard during the hottest part of the summer (in NM; it gets well over 180 in a closed car) and fire the rounds just before the first snow.32, 380, 38spl, 357mag, and 9mm didn't show any appreciable variation over the screens of my chrono-270wby, 30carbine, and 300win mag all showed velocities 12-30% HIGHER and showed some case bulging as well. My conclusion was not to put any more ammo on the dashboard when it's not 68F or cooler.

    Loaded gun in "hot" car. Depends on your definition of "hot".

    General opinions (of those I've seen over time on these Forums) seem to indicate that: no, neither high nor low temps affect ultimate performance of competenty loaded ammo. Low temps may adversly affect stored powder that is then used to load new ammo however, but this was one isolated response.However, should you fire ammo that's just been sitting under elevated temperature conditions, without allowing the ammo to cool down to "ambient" temps, the chances of a nasty high-pressure case failure is much more likely. Please use caution in this circumstance.edit: dang; gotta' check my speling more closly before hittin' "send."[This message has been edited by spclark (edited 04-07-2002).]
