I bought a new 97k these came with it .. they were loose and a few fell out .. if i wasnt a seasoned 97 owner if have dry fired or loaded with a pellet trapped between breech and barrel either way causing one of my seals to perrish ,, stick to crosman . I buy a box of 1250 a fortnight without fail .. dont scrimp on lead .. can cost more than you save mate
