MythBusters : Ammo in a Hot Oven
Did anyone see tonights episode ? I wont spoil it for the results but they asked whether ammunition in a house oven at normal temps will set the ammo off and also if a loaded gun in the oven will fire.

who stores ammo or puts guns in the oven? 0 -
According to press reports alot of people do. One story was from a man who put some extra ammo boxes in the oven because they were moving some furniture around and he forgot about it. Later his wife turned on the oven to pre-heat it and BAM !! 0 -
Well let's just say I wasn't surprised. It, along with 'shooting a bullet straight up' have been tested many, many times. I've never seen a round that some idiot threw into the burn barrel at the range ever even pierce the side of the barrel.
Now the bull in a china shop, that was far more interesting and surprising.0 -
I thought that England and a few other countries have already tried this.
You know placing all of the decent citizens guns in ovens down at the local steel mill.
MythBusters... About as big of a joke as that show Jackass.0 -
I enjoyed the part about the bull in the china shop, too.
Now let's see them take on the following myths:
Will taking my guns away make anyone safer? (I'm betting "no")
will taking the bayonet lug off my ar-15 make anyone safer?
will limiting me to 10 rd mags make anybody safer?
outlawing pistol grips?
ballistic fingerprinting?
all the other crappy legislation?0 -
The show is not too bad when they are fooling with guns and blowing stuff up. They should stick to that plan for all their shows![:D][8D] 0 -
I didn't see the MythBusters show, but I have seen old cowboy movies where the good guy would through a handful of cartridges into the campfire to make the bad guys think they were surrounded by good guys. Worked real good in the movies.
Sooo, naturally I had to try it. I threw a handful of .22s and a couple of .410 shells into a campfire and took cover. One of the major disappointments of my childhood. There were a couple of almost silent pfff's, but for the most part nothing happened.
There have been some pretty serious fires in places where large quantities of ammunition was stored and didn't even melt the lead. It may be possible to get the bullet to separate from the brass without being in a firearm, but it wouldn't be an easy trick. I have seen a couple of cases where a loaded weapon supposedly "cooked off", but I still believe those were "cover stories".0 -
I bet if they had put more than just one bullet in the over they would have had different results. 0 -
So, what kind of result did they get? 0 -
the results were this....
when the placed ammo by itself in the oven it would explode at about 470 degress but it would expell the bullet like it was shot. it would merely explode and basically do no damage.
However, when the placed a handgun with a live round in the oven it fired the round at about 500 degress just like if you had pulled the trigger.0 -

But the ammo by itself would not break the glass and go all over the place. But they only used one round of each type of ammo. Put a typical box of 50 rounds in or a brick of the .22 and see what happens.0 -

some of you are missing the point, i know they get some of their facts turned around BUT THEIR PRO 2ND ADMENDMENT
we need more shows like this, but with a bit more help from experts to help us debunk some common firearm myths, you know the type they teach at media school, and the dnc0 -
are they really pro 2nd amen ? i was wondering what their position was considering they are guys who work in hollywood but have their shop in the bay area (very anti-gun)
i have been very pleased to see a show that uses guns so often and doesnt always have to put in some liberal disclaimer all the time like "look kids, guns are bad, but we are just doing science"0 -

You would get exactly the same result. The physics of this are simple.
I am sure most of you already know this but humor me. The sequence of events to fire a round is such. Hammer (or firing pin) strikes the primer. The charge in the primer is detonated and ignites the powder. As the powder burns (smokeless powder does not explode, it burns, hence the term "burn rate") it produces gases. Those gases want to expand. The bullet and the case initially keep those gases contained within the round. As the powder continues to burn the gases continue to build up causing the pressure (force) within the case to increase. The pressure needed to push the bullet out of the brass is pretty low. When the bullet reaches the lands of the barrel, the resistance to movement is increased greatly. Therefore, more pressure is needed to push the bullet down the barrel. The powder is still burning creating more gases and more pressure. These gases are now being contained in the case and barrel (a small volume) allowing the pressure to reach very high levels and pushing the bullet down the barrel faster and faster. Once the bullet leaves the muzzle, the gases escape into the atmosphere. At that point the bullet ceases to accelerate and the pressure within the barrel returns to atmospheric.
So, if there is no barrel to contain the gases with a small volume, there is no pressure build up and the only acceleration that the bullet will get is that which is enough to push it from the case (which isn't much).
This explains why a round that is places in the oven or in a fire will only puff and the bullet will not have much energy. But, if you put a loaded gun in the oven or in a fire, it will "fire" like it would if you pulled the trigger.0 -
i always wondered how it happened, i guess it wasn't magic after all[:)] 0 -
I've seen a house that burned down because little Sally hid her toy dolly in the oven. Mom went to pre-heat the oven and went outside to finish some yard work. 0 -
I recall reading a news report several years ago about a house fire in rural Florida. A volunteer firefighter moving around out in the yard received a fatal gunshot wound from a cook-off round out of a loaded/chambered .22 rifle inside the house.
Talk about some tall odds...0
