The number of BBs that make up 2.5 ounces depends on the size and weight of each BB. Standard airsoft BBs typically weigh 0.12 grams each, while steel BBs can weigh around 0.35 grams. To convert ounces to grams, 2.5 ounces is approximately 70.87 grams. Therefore, for 0.12-gram BBs, you would have about 590 BBs, while for 0.35-gram BBs, you would have around 202 BBs.
.25 Airsoft bbs can be good. Their weight is very good for accuracy and helps for a harder hit from the bbs. However, no bb is good if they are not high polish. Companies like Madbull and Matrix make good .25 bbs.
