BBs are typically made of steel. BBs are often coated with either zinc or copper to prevent corrosion and rusting. The coating of zinc or copper on the BB doesn’t affect performance. Choosing one or the other comes down to a preference in what you want your BB to look like.

Modern BBs are designed for 4.5 mm in diameter or .177 inch/caliber gun barrels. By design, the BBs are very slightly smaller than that to ensure they travel smoothly down the barrel of the pistol or rifle they are being fired out of. The standard BB typically weighs between 5.1 to 5.4 grams.
