Which of these is the largest bore?

  1. 10 gauge

  2. 12 gauge

  3. 20 gauge

  4. 16 gauge

The correct answer is: 10 gauge

The 10 gauge is the largest bore among the options provided. In shotgun terminology, the gauge of a shotgun indicates the diameter of the barrel; a smaller gauge number means a larger bore size. The 10 gauge bore is approximately 0.775 inches in diameter, making it wider than the 12 gauge (which has a bore diameter of about 0.729 inches), the 16 gauge (approximately 0.669 inches), and the 20 gauge (about 0.615 inches). Because gauge refers to the number of lead balls of a diameter equal to the bore that would weigh one pound, a lower gauge number indicates a larger size. This is an important concept in understanding shotgun performance, as larger bores can fire larger or heavier shots, impacting factors such as recoil and the type of game that can be hunted effectively.
