What are the pluses and minuses of the two types of powders? What powder is generally better for what application? Thanx-

Double-base powders generally burn a bit hotter than single-base powders. This used to be a problem with the older, softer steels.

Double-base powders also have always had the reputations as being a bit dirtier.

Other than that, there's really not any particular reason to pick one over the other in performance issues.

Single base powders are nitrocellulose, double base powders are nitrocellulose and nitroglycerine. (Aside from stabilizers, deterrents, and additives in each type.) Double base powders generally pack more chemical energy per grain . . . the advantage is that, as a rule of thumb, the double base powder that requires the heaviest charge to achieve - but not exceed! - maximum safe chamber pressure will usually produce the most velocity with a given bullet.
