[QUOTE="Catfur, post: 842572, member: 41271"] Short answer, both nitrocellulose (found in single base propellants) and nitroglycerin (found, in addition to nitrocellulose, in double base propellants) are high explosives. This means they detonate (the flame front when they burn moves faster than the speed of sound through the substance). They are stabilized for use as smokeless propellants, so that they deflagrate (flame front moves slower than the speed of sound) instead, when used in a firearm. Under certain conditions, they will revert to detonating, and this can damage/destroy your firearm (and you). One condition that has, VERY RARELY but not zero frequency, been demonstrated to cause this is a slow burning powder that is loaded under the minimum charge. It happens infrequently enough that it is very hard to characterize, but often enough that we know it CAN happen. [/QUOTE]
