What is nominal bore size 12ga shotgun?
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 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.
What gauge shotgun would have a 40 mm bore?
A shotgun with a 40 mm bore would correspond to a 10-gauge shotgun. The gauge system is inversely related to the diameter of the bore; thus, a 10-gauge shotgun has a bore diameter of approximately 0.775 inches (19.7 mm), while a 40 mm bore exceeds the common shotgun gauges. However, 40 mm is typically associated with larger caliber weapons rather than standard shotguns.
What is the diameter of a 12 bore shotgun cartridge?
0.729 inches or 18.5 mm
What is a 410 shot gun?
This is a shotgun with an internal barrel diameter (called the "bore) of approximately .410" which shoots a shell which is about .410" in diameter. It is the only shotgun shell size that uses this convention. A 12 gauge shotgun, for example, does not have a bore of "12". A 20 gauge shotgun has a smaller bore than a 12 gauge and a 10 gauge has a bigger bore than a 12. Gauge size is based on the number of lead balls of the bore diameter which are required to make a pound (16 ounces). 10 balls, 12 balls, or 20 balls.
What is a bore on a shotgun?
Bore is the number of lead spheres the diameter of the barrel it would take to equal one pound. Ergo, the larger the bore, the smaller the barrel.
How big is a 12 gague?
A 12-gauge shotgun refers to the diameter of the shotgun bore, with the gauge system indicating the number of lead balls of the bore's diameter that would weigh one pound. In a 12-gauge, it takes 12 lead balls of the same diameter to equal one pound. The bore diameter of a 12-gauge shotgun is approximately 0.729 inches (18.5 mm). This gauge is one of the most popular sizes for shotguns, commonly used for hunting and sport shooting.
What is a 4.10 shotgun?
I believe you are referring to a .410 (pronounced four ten) shotgun. This is a shotgun chambered in .410 caliber, which is different from other shotguns that are measured in gauge.
What is rifle bore?
The bore is the inside of the barrel of the gun. Bore dimension for most rifles is caliber, which is the bore diameter in fractions of an inch or in millimeters. Some older big game rifles had designations such as "12 bore", which is bore diameter the size of a shotgun barrel of the same gauge. Gauge is the number of round balls fitting the bore that can be made from a pound of lead.
Where does shotgun gauge come from?
Think of a lead ball which is the diameter of the inside of the barrel of the shotgun. The gauge of the shotgun is the number of balls that size to make up one pound. 12 balls - 12 gauge 20 balls - 20 gauge 28 balls - 28 gauge Exception - .410 bore is the actual bore diameter
What does 20-gauge mean?
A 20-gauge refers to the size of a shotgun, indicating the diameter of the shotgun bore. The gauge number is inversely related to the size of the bore; specifically, a 20-gauge shotgun has a bore diameter of .615 inches and is smaller than larger gauges like 12-gauge. The 20-gauge is popular for its balance of manageable recoil and effective performance, making it suitable for various hunting and shooting activities.
