not a verb. you can not gauge.

you can stretch a piercing you can not gauge it. it would be like saying "I'm going to large" its what Sizes are referred to. NOT a verb.

the bigger the number the smaller the hole. 18ga is a standered ear piercing size.. when the numbers get smaller ex, 16, 14, 12... it means the hole is bigger.

i have a 12 gauge piercing

With a smaller pellet diameter than all other sizes of buckshot, birdshot grants you a larger number of pellets per shot. But even though birdshot is a versatile ammo choice, it isn't ideal for use when hunting deer, moose, bears or other large game. Most use steel birdshot for hunting waterfowl (duck) and predator control.
