You can blow up a rifle with any kind of powder. If I remember correctly, all the loads in Wright's books were tested and proved safe in his or friend's rifles that he shot. Quite frankly, I found it refreshing to read a book by someone who has been there, done that, and was doing it long before me, without having the F*****g "do not use this load because I only got it off quickload and don't want you to sue me" message every other sentence, as you find in virtually all US articles.
