20 gauge is a type of ammunition for firearms. It is classified as a (S)hotgun caliber.

20 gauge is a middle step in size between the diminutive .410 bore shells and the larger 12 gauge shells. They offer a good compromise of recoil and power, but at the cost of not being able to fit as many projectiles in the shell. Some projectile types are not available in 20 gauge (namely, FRAG-12 and coin shot) as they simply would not fit. All 20 gauge shells in the Mazes are 2 ¾ inch (70mm) long.

This caliber may also be called 20 ga. or 20G.
