Thanks, Rich and Dan.
Dan: I know Orion sells an insert that allows the 25mm gun to fire the 12mm flares.
But, I never heard of a 38 bullet insert. Homemade??? I've read about how
the 25mm gun with the insert which Orion sells can fire 12 gauge shells (like
that fired by a 12g shotgun) but haven't read particulars and don't see offhand
what an insert which allows for 12 MILLIMETER shells would fire 12 GAUGE shells
- buit, admittedly, I'm not a firearms expert.
