Jon, Get yourself some once fired 9mm brass, take a glue stick and carve it to fit inside the case. Shape like bullet and you be done.
If you would like to have some "snap caps" punch out the old primer and replace it with a piece of eraser off the end of a pencil. Then fill the forward end with a piece of glue stick. IF you need something more robust. Pick up some dowel from your nearest home improvement store just larger than what would fit easy into the 9mm case and sand, paint and glue yourself up what you need.
Hope this helps.
Thank you for the info, but I like to have FMJ heads,
Does that eraser thing really work... I wanted some snap caps but that would be easier(read cheaper)
