Hammer Zero Mercy Solid Bowling Ball — Maximum Traction, Violent Continuation, Hammer’s Strongest Ball Ever Built

A Maximum Oil Statement

Hammer rarely uses absolute terms to describe its own equipment. The Zero Mercy Solid, however, is the exception. Released in November 2025, this ball claims the top of the Hammer performance range outright. Driving the motion is the Super Offset asymmetric core. Surrounding it: HK22C² Solid, Hammer’s most aggressive coverstock ever. Additionally, the Chrome additive pushes this formula beyond any previous HK22 version. At 500/1500 SiaAir box surface, moreover, it grabs heavy oil conditions hard and holds on.

Ultimately, this is not an all-conditions ball. Heavy oil is specifically where it belongs. That said, surface adjustment can extend its range — though its design intent is the box finish on volume oil. The four-color identity — Black, Purple, White, and Red — matches the ball’s personality. Nothing about the Zero Mercy Solid is subtle.
