If you tear blade tape into 3mm wide strips and then wrap it round a 9mm. round where the extraction recess is it will build up a ridge that will hold the bullet nicely so it can be fired by a Smith & Wesson 0.38. Unfortunately it is not robust enough for the extractor to pull the cartridges out so you have to poke them out with a screwdriver.
It doesn't 'alf go.
