A ball is a round object (usually spherical, but can sometimes be ovoid) with various uses. It is used in ball games, where the play of the game follows the state of the ball as it is hit, kicked or thrown by players. Balls can also be used for simpler activities, such as catch or juggling. Balls made from hard-wearing materials are used in engineering applications to provide very low friction bearings, known as ball bearings. Black-powder weapons use stone and metal balls as projectiles.
Although many types of balls are today made from rubber, this form was unknown outside the Americas until after the voyages of Columbus. The Spanish were the first Europeans to see the bouncing rubber balls (although solid and not inflated) which were employed most notably in the Mesoamerican ballgame. Balls used in various sports in other parts of the world prior to Columbus were made from other materials such as animal bladders or skins, stuffed with various materials.
As balls are one of the most familiar spherical objects to humans, the word "ball" may be used to refer to or describe spherical or near-spherical objects.
"Ball" is used metaphorically sometimes to denote something spherical or spheroid, e.g., armadillos and human beings curl up into a ball, we make a ball with our fist.

    Washington  Crystal ball time, how do u think WA mag ban will be enforced & to what extent?

    Was thinking about Colorado magazine ban from years ago. My understanding is to anyone in the gun community it was kind of viewed as a joke and many retailers were even selling standard cap mags that were blocked to 10 round size along with kits to return them to normal capacity. Forgetting...

    Washington gun stores that sell milsurps/odd ball ammo.

    Hello are there any western Washington gun stores that carry good amounts of milsurps? More importantly though is there any stores that carry ammo that isn’t “common”. I’m mostly looking for .303brit, 8mm Mauser and 7.65argentine.
