Have one of these standing in a corner. Bore mics at about .304-.306. Heavy octagon barrel.

Is there any use for these things beyond tomato stakes or pry bars ??

You could donate it to the Digital Dan research facility.

Sorry, I'm busy developing the .22 BB CF Short (AI) Creedmoor.

I have heard of them being relined to 22 short. S&B sells 22 & 6mm Flobert RF ammunition. Not that valuable but cool rifles that would be fun to shoot.
