Product Review; "Copperhead BBs by Crosman are a great choice for inexpensive plinking, or medium range small game hunting. The spherical shape is not the most true-flying or aerodynamic, but a bottle of 6,000 costs less than $20, so it's easy to keep some around for the shots where accuracy doesn't matter as much - I highly recommend for any Air Gun shooter!" -MadeInUSAReview

Only use Amazon links for info or if only option, some businesses don't have the means to distribute their own products, but using sites like Amazon should always be the last option
