I now see why Remington advertised their double guns, whether composite or fluid as "Guaranteed for Nitro Powder". Scott K. brought his tools with him to the trap range last night.
Bores are L - .790 with .045 of choke, R - .789 with .046 of choke, choke taper is about 4 1/2" long.
Barrel walls about 1 inch in front of forcing cone are .165 and about 8 inches from the muzzle they measure .100
