With its Rough Buff finish, the Brunswick(r) Loaded Revolver bowling ball unites the proven Propel X(tm) Pearl coverstock and the Jack(tm) low-RG core to produce a ball motion that clears the front with ease and is aggressive in the mid-lane, with a quick, continuous response to friction on the backend. The high differential increases track flare potential, giving the ball more opportunity to grip the backend while using standard layouts.
