Velocity necessary for a BB to penetrate the eye: an experimental study using pig eyes.

Purpose: To determine the V-50 threshold velocity needed for a steel BB to penetrate the eye of a 230-pound pig.

Method: BBs were shot at a distance of 10 feet into the corneas of pig eyes with a pump-action BB gun.

Results: The V-50 velocity for corneal penetration and serious disruption of the eye was found to be 246 ft/sec.
