I was bored the other day and made this to pass the time. It is a supplemental chamber so you can shoot .32's in a 20 gauge shotgun. This one is rifled and will use .32 S&W shorts and longs. I will try it soon. It should be fairly quite(I hope). I also made a 20 gauge to .410 adapter earlier. Neither are practical but are functional.
Just walking on the edge of of my grave.
