I have a very nice Westley Richards boxlock double in 32-40, as originally chambered by WR in the 1920s. It will shot nice groups with inexpensive American commercial loads, and the function of the gun is an absolute pleasure. (Ejectors leave me two neat piles behind me on either side of the shooting station at the end of a session.) This is a very good choice for a low recoil, low cost light hunting load for a DR. Dave
