Apparently this thread brought out all the clowns who think non-temp-stabilized double base powders aren't temp sensitive.
Some of us don't have to pontificate about the theoretical behaviour of these things, because we've actually tested them in a variety of circumstances. We KNOW that certain powders are temp-stable in a wide range of applications, despite what your assumptions or Google results may say.
There's really not all that much to it, but of course lots of marketing chaff being blown by companies with an interest in selling non-stabilized powders. In the end I don't give a flying [bleep] what you put in your rifle, but the facts are the facts.
In the end theory is theory, and facts are borne in experimental results.
