Tightgroup, AA2, and Red Dot, are all generally considered to have the same burn rate.

BUT THAT DOES NOT MEAN THAT THEIR LOAD AMOUNTS ARE INTERCHANGEABLE.

When switching powders, new recipes must be made, and any load data from the "old" powder must be disregarded. They may have the same burn rate, but they are still "apples n oranges," so to speak.
