  • Bullet trap and a method of using it
    Patent number: 4846043
    Abstract: A bullet trap comprises a lid over a container body holding aggregated, randomly- or not-randomly-arranged swatches of one or more types of polyacrylamide fiber material or the like. The lid is penetrable by bullets and the aggregated swatches slow any bullets which penetrate the lid sufficiently to retain them in the container. The bullet trap is intended for use in a method of safely loading and unloading firearms in which the firearm is aimed at the trap during loading and unloading to trap any bullets accidentally discharged during loading and unloading.
