I am looking at a gun that I suspect may have been set up for box bird shooting. It is a 1920's British O/U set up as follows:
1. Double tapered file cut solid Rib
2. Triggers switched per original factory order (Front fires left lock as if set up for a left-hander--top strap cast for a righty)
3. Weight 6 3/4 lbs.
4. "Grouse choked" (.039 front trigger/.023 back trigger)
5. Slight matched overbore .005
6. 2 1/2 chambers, 28" barrels
7. DAC 2 1/8
My working theory is that the first barrel fires the first XF shot at the bird with the greatest chance of disabling it, and the second, rear, trigger is slightly more open for a follow up shot, if needed. Points #3 and #6 seem to cut against the theory, and perhaps it was some sort of a compromise order. I would love to hear other theories as to why someone would set up a gun in this fashion.
