The Loaded Revolver maximizes its performance by using Propel X™ reactive coverstock technology. Propel X™ features an enhanced pore structure to provide Xtra consistency from shot to shot and Xtra workability on a wider variety of lane conditions. The Jack™ core was designed as a Low RG symmetric core with a high differential. The Low RG engages in the midlane assisting in ball motion, and the high differential increases track flare potential giving the ball more opportunity to grip the backend while using standard layouts. With its Rough Buff finish, the Loaded Revolver unites the proven Propel X™ coverstock and the Jack™ Low RG core to produce a ball motion that clears the front with ease and is aggressive in the midlane with a quick, continuous response to friction on the backend. The Loaded Revolver can be drilled using the standard drilling techniques developed for symmetric bowling balls. The unique core shape of each Brunswick ball is used for weights from 14 to 16 pounds. This approach to lightweight ball engineering provides bowlers with consistent ball reaction characteristics across this weight range. The same drilling instructions can be used for 12and 13pound balls. This is because Brunswick uses a generic core shape with an RG differential that is close enough to the 1416 pound shape.
