Crosman Premier Piranha Hollowpoint pellets feature a rounded top with a star-shaped indentation. Crosman calls it the "shark tooth edge." The Piranha delivers the penetration of a domed pellet with the expansion of a hollowpoint for the best of both. Made in the USA and compatible with .177 caliber air rifles and pistols only, the Piranha is a great choice for hunting small game or nuisance animals.
