[QUOTE="Weaver93, post: 2666771, member: 120245"] Here is one of the articles I read: " The degree to which these propellants are flattened is carefully controlled to slightly stress the grains. This improves the cold temperature performance of the Ball powders. The stressed grains at cold temperatures tend to fracture somewhat, which increases the burning surface area slightly, increasing the gas production rate and reducing the pressure and velocity drop at cold temperatures. There is a fine line though. If the propellant grains are flattened too much, the pressure at cold temperatures can go up substantially."
