That's what several of us guys do that shoot the Swedish Mausers. Pull the wooden bullet. Reuse the powder in revolver rounds and some other handgun stuff. Push an expander ball through the now-just-primed-brass, load with a match powder and bullet and win vintage rifle matches! Then just toss the brass because it's not worth repriming the Berdan stuff, even though that's what they did to make the blanks in their factory (it itself is reloaded once-fired surplus). This is especially useful in the semi-auto AG-42B Ljungman rifles because they really beat up and throw brass.
