Hammer Zero Mercy Solid Bowling Ball

The Zero Mercy Solid pairs Hammer's asymmetric Super Offset core with the HK22C2 Solid Reactive coverstock at a 1500-grit finish. At 15 lbs it carries an RG of 2.524, a strong .053 differential, and a .020 mass bias - numbers that produce high track flare and a defined, asymmetric breakpoint. The sanded solid cover reads the midlane early with strong traction, so the ball gets into a hard roll on real oil and drives continuously through the pins rather than rolling out. Because the core is asymmetric, layout has a strong influence on the reaction, giving your pro shop room to tune how early and how strong it plays. It ships in a Black/Orange/Purple/White colorway.
