[QUOTE="River Man, post: 165385, member: 9084"] I too have long wondered how far down the barrel the powder burned. I have shot AR-15 carbines with 16 inch barrels without flash suppressors well after dark. The flash is blinding. There is an oblong bright white and yellow fireball that is about 6 inches in diameter and about 10 inches long. This is from a 223 cartridge that holds about 25 grains of powder. Why would you get such a large fireball if the powder burned in the first few inches of the barrel? Could it be super hot gasses glow? I don't have an answer. I always assumed it was powder still burning. [/QUOTE]
