I got my Caldwell chronograph from the Bass Pro Shop in rapid city.
I tested it in our motel room with paper wads in a straw.
Good holiday.
Repariere nicht, was nicht kaputtist.
If you're still looking, I've got one of the combro ones you attach to the end of the barrel (Combro CB625 mk4) - Welcome to borrow but if you make me a reasonable offer I'm sure we can sort something out. I'm in SO30
