Considering all things (shootability, collector value and cool factor) what would you suggest in getting these barrels functional?
Here are the facts. (all measurements performed by Pete Mazur using a Delta Ultrasonic PX-7 Gauge)
Left Tube Right Tube
Bore *.741 .732
Muzzle .700 .731
Choke .041 .001
Minimum Wall .040 .043
Wall @ Muzzle .060 .0455
*Bore dia. @ 9" from breach .741, @18" from breach .739, @24"-27" from breach .736.
Report:
Left Tube- Very smart dents 21" on top of tube that can be polished out.
Right Tube- Several dents 24" on top of tube that have been poorly raised. These dents must be repaired if this gun is to be shot.
These barrels are in very good over-all condition. PM
If both bores were opened to .742 it would add .010 choke to the current cyl choked right tube. Opening the left choke to .712 would leave a .030 choke. 010/030 chokes are a pretty nice combination. The draw back is reducing min wall thickness to .033 on the right tube and .050 at muzzle on left tube.
U.S. ANS Z299.2 Maximum Bore Diameter is .745, England 1954 is .750 and Germany 1939 is .7323
It is a bit barrel heavy so I have no problem taking some metal off here and there IF it does not jeopardize the safety of the gun. But I have no clue as to the minimum wall thickness for Damascus steel.
