The nominal bore size of a 12-gauge shotgun refers to the diameter of the shotgun's barrel, which is approximately 0.729 inches (18.5 mm). The "gauge" system measures the number of lead balls of the bore diameter that can fit into a pound; thus, a 12-gauge shotgun is designed to accommodate 12 lead balls of that diameter. This measurement influences the shotgun's performance, including its shot pattern and recoil.

What is pipe bore?
Pipe bore is the actual minimum inside diameter of a pipe, which is not necessarily the nominal pipe size.
What is mean by NB in using valve measurement?
NB stands for "Nominal Bore" and refers to the nominal size of the valve in a piping system, typically measured in inches. It represents the internal diameter of the valve or pipe. It is an important parameter used to select the right valve for a specific application.

What is is the OD of a 40 inch nominal bore blak steel pipe?
The outside diameter (OD) of a 40-inch nominal bore black steel pipe is typically 40 inches, as the nominal size refers to the approximate internal diameter of the pipe. However, the actual OD for standard pipe sizes can vary; for a 40-inch nominal bore, the standard OD is approximately 42.16 inches according to the American National Standards Institute (ANSI) specifications. This discrepancy is due to the wall thickness of the pipe, which is accounted for in the nominal size.
What is barrel diameter of 410?
The .410 shotgun has a bore diameter of approximately .410 inches, which corresponds to the nominal size. However, when referring to the barrel diameter, it can vary slightly based on the specific design and manufacturer. Typically, the barrel diameter for a .410 shotgun is around .410 inches at the muzzle.

What do you mean by nominal diameter in pipes?
NB (nominal bore) is the European designation equivalent to NPS is DN (diamètre nominal/nominal diameter/Durchmesser nach Norm), in which sizes are measured in millimeters.

What is the bore a shotgun barrel made specifically for?
The bore of a shotgun barrel is specifically designed to accommodate the size of the shotgun shell and its intended projectile, typically a wad or shot. The diameter of the bore determines the gauge of the shotgun, which influences the type and size of shot that can be used effectively. A properly sized bore ensures optimal performance in terms of accuracy, range, and pattern spread when firing. Additionally, the bore may be designed with specific features, such as choke constrictions, to enhance shooting characteristics for different applications.
What is the difference between a 410 and a 12 gauge shotgun?
Size of the bore. 12 gauge is bigger.
What is the a measure related to the diameter of the bore and the size of the shot shell designed for the bore?
The measure related to the diameter of the bore and the size of the shotgun shell is known as "gauge." The gauge is determined by the number of lead balls of the bore diameter that equal one pound; for example, a 12-gauge shotgun has a bore diameter that allows for 12 lead balls of that diameter to weigh one pound. The smaller the gauge number, the larger the bore size. This system is commonly used to classify shotguns and their corresponding ammunition.
