Question:
A topic I don't see really addressed in the FAQ or in the NRA basic safety information is what happens to your ammunition during a fire. I'm assuming that the primers ignite, the cartridges go bang, and you don't want to be anywhere near them. What do people do to store ammunition such that it isn't a hazard in a house fire? Are inexpensive home safes sufficiently bulletproof that ammunition could be stored in them to contain the damage?

Answer: -Yes, sort of. One of the gun mags (may have been American Rifleman) did an article on this recently, and they determined that you get a bit of noise, but the bullets don't really move much at all, since there's no way to build up much pressure behind them. Ammo actually chambered in a gun, I suppose, would go off pretty much normally, though.

-There was an article on this in the AMerican rifleman about a year ago. Usualy the powder cooks off, the case splits, and the bullet goes about 2 inches. The primer will often leave the case with enough velocity to dent drywall however. The only way ammunition would be dangerous in a house fire is if it is in the chamber of a firearm. If so, and the round cooked off, the chamber would suport the case, and the round would go off as normal.
