# What are the dimensions of a 12-gauge shotgun shell?

## What are the dimensions of a 12-gauge shotgun shell?

Modern 12-gauge shotshells come in 2 ½-, 2 ¾-, 3-, and 3 ½-inch lengths, all holding different amounts of powder. Shotguns are marked on the barrel, for example: 12-gauge 2 ¾ inch. This shotgun’s maximum shell length is 2 ¾ inches.

What is the OD of a 12-gauge shotgun shell?

Standard

Gauge (number of lead balls in one pound) Diameter of one ball
inch millimetre
12 0.729 18.5
16 0.663 16.8
20 0.615 15.6

What’s the diameter of a 12-gauge slug?

around 0.690 inch
The diameter of the wad slug is slightly less than the nominal bore diameter, being around 0.690 inch (17.5 mm) for a 12-gauge wad slug, and a wad slug is generally cast solely from pure lead, necessary for increasing safety if the slug is ever fired through a choked shotgun.

### What is the breach of a shotgun?

Breaching rounds are designed to destroy door deadbolts, locks, and hinges without risking lives by ricocheting or by flying on at lethal speed through the door, as traditional buckshot can.

Can you shoot open a locked door?

Advertisement: In movies and television, a locked door, or a padlock on a cage is never an impediment so long as the Hero has bullets to spare. One or two shots is generally enough to destroy the lock, allowing the door to open.

How big is a 12 gauge shotgun bore?

The internal diameter of a 12 gauge shotgun barrel is therefore equal to the diameter of a lead ball weighing 1/12 pound, which happens to be .729″ (Or in British: Bore.)

#### How is the diameter of a 10 gauge shotgun determined?

The gauge number is determined by the weight, in fractions of a pound, of a solid sphere of lead with a diameter equal to the inside diameter of the barrel. So, a 10 gauge shotgun nominally should have an inside diameter equal to that of a sphere made from one-tenth of a pound of lead. Each gauge has a set caliber.

Which is the smallest load in a 12 gauge shotgun?

Sometimes called the “dove shot,” this is about the smallest legitimate hunting load. With pellets that are .1 inches in diameter, this load can be used for doves, pheasant, and ducks, assuming they are within close range. This is also a versatile load that can be used for smaller game and trap if necessary.

What kind of barrel does a Browning 12 gauge have?

Current Browning 12 gauge barrels are neither. It is fallacious to assume that any individual gun has either of those exact bore diameters-one of the reasons we need to mic our bores to begin to uncover the constriction / patterning relationship in an individual gun.
