[QUOTE="Kennibear, post: 910080, member: 51650"] The protocol is called a " closed bomb test" with a high tensile strength steel sphere w/ pressure gauge. Fixed amount of powder is set off and pressure curve is recorded. Secondary after that is a SAAMI test gun firing. Another factor is energy density. Separate from the load density double based powders have more energy per unit weight. Even though the burn rate is the same you use less as DB powders have higher energy content. It's just very complicated to reduce it all to a single table. Hodgdon puts out a good rate table and their 2014 Mannual/Magazine just hit the stands. Got mine yesterday. KB [/QUOTE]
