Shotgun barrels in the US must be at least 18 inches long, and are generally smooth inside. Handgun barrels are usually much shorter than 18 inches, and are rifled- a set of spiral grooves (rifling) is cut into the inside of the barrel to make bullets spin when fired.
According to section 202.275 of Nevada State law: a "Short barreled shotgun" is:A shotgun with one or more barrels that has an overall length of less than 26 inches, and or,a barrel length of less than 18 inches
Short barreled shotgun is actually a legal term- it means a shotgun that has barrels less than 18 inches, or an overall length of less than 26". To my knowledge, H&A did NOT make a short barreled shotgun. Information is thin- they went out of business about 1914-1916, but all listings I have seen are for 28 inch barrels.
check with the MI State Police. MI appears to follow the Federal law, which requires a barrel length of at least 18 inches, and overall length of at least 26 inches. From Michigan State Code, Firearms, Definitions: (i) "Short-barreled shotgun" means a shotgun having 1 or more barrels less than 18 inches in length or a weapon made from a shotgun, whether by alteration, modification, or otherwise, if the weapon as modified has an overall length of less than 26 inches.
The barrels by inch in a 100 barrel tank refers to the amount of oil the tank can hold per inch of liquid depth. To calculate this, divide 100 barrels by the tank's height in inches. For example, if the tank is 60 inches tall, the barrels by inch would be 1.67 barrels per inch (100 barrels / 60 inches).
To find the number of barrels per inch in a 210 barrel tank that is 15x10 inches, you would multiply the dimensions to find the total volume in cubic inches (15x10 = 150 sq inches). Then, divide the total volume by the number of barrels (210) to get the barrels per inch. In this case, 150/210 = 0.714 barrels per inch.
To calculate the number of barrels in a 400 barrel oil tank per inch, you would need to divide the total capacity of the tank (400 barrels) by the height of the tank in inches. For example, if the tank is 100 inches tall, there would be 4 barrels per inch (400 barrels / 100 inches = 4 barrels per inch).
The length of a shotgun barrel is federally regulated and is 18 inches. Barrels come in 18 inch length's but i recommend the 18.5 inch barrel, just in case guys measuring has a old knarled up measuring tape.
Firstly you need a time basis for the inches?
36 inches
Pistol barrels range from 2" to 12", and almost every increment in between. Longer barrels increase accuracy, shorter barrels make for more compactness.
Most are full or modified unless the barrles have been shortenedThere are different barrel lengths- legally, anywhere from 18 inches, out to about 32- although most are 26-28 inches. The external diameter may vary some, but not a lot.
