In a Martini-related vein..
I once had a .22 target rifle built up in a BSA "Cadet" action. The barrel was substantial, to say the least.
The interesting part was that the barreled action was fitted with an equally substantial, one-piece stock.
The "bedding" was interesting in that it was the barrel that was bedded, with actual clearance (small) around the action. The lever was reshaped to curve down the front of the "thumb-hole" pistol grip.
With Eley "Match" it would produce nice, tiny groups, once you got used to the trigger.
Eventually sold it to a collector of small-bore target rifles.
Anyone seen anything else like that?
