What are the "nominal" specifications of an 8 gauge? SAAMI does not publish a drawing for 8 gauge.
My 10 gauge Serial Number 18843 has 32 inch barrels and weighs 10 lbs 5.8 ounces.
Width of he breach balls is 2.752 inches
Firing pin spacing is 1.353 inches center to center.
Chamber wall thickness is .349 .279 inches measured in front of the extractor cuts.
Barrel thickness measured at the muzzle is .072 (right) and .0765 (left).
I don't have a bore gauge so I don't have an accurate measurement of bore diameter and choke constriction.
