Brian, thank you. Would it be uncommon to see a gun from the early 1900's with different bore diameters in the same set of barrels? I have a set that measure .736 and .740. Thickness averaging out to:
RB .041 and LB .054. I had them inspected and they were safe to shoot. I just want to learn more about the whole process. |

Usually the bore diameters from tube to tube will be close. But a few thousanths is not out of the ordinary.

I once miked a 1911 CHE pigeon gun that measured .750 in both bores at midpoint.

Not a Parker but "Choke Bored?" |

Not a Parker but "Choke Bored?"
I picked up a basket case 12 gauge Crescent Arms gun and had my brass gauge with me. It told me there was still choke left in the gun, being modified and modified. The barrels were stamped "Choke Bored."
When I got home I measured the bores and both were .710 all the way to the end, cylinder and cylinder in cut barrels. I am wondering what advantage did they gain by deviating from the standard .729 and the gun is hammerless so it had to be made when there was some standardization in the 12 gauge bores. I wish I could have know how much choke was put into the gun to achieve a hardware store gun with probably full chokes. |

Many European guns have bores in the vicinity of .720
