Hammer Special Effect Bowling Ball

An Early-Reading Asymmetric Benchmark for Heavy Oil

About the Special Effect

The Hammer Special Effect is the early-reading, traction-first member of the Effect line. It pairs the asymmetric Huntsman Core with the HK22 Cohesion Solid coverstock, delivering strong flare and an early, defined read on medium to heavy oil. It is a controllable, hard-driving benchmark for the heavy part of the block.

The Special Effect reads early and rolls strong. The asymmetric Huntsman core stores energy for a defined breakpoint, while the HK22 Cohesion Solid cover digs into the midlane. The result is a strong, predictable asymmetric that gets into a roll quickly and continues hard through the pins.

Understanding the Hammer Huntsman Core and Hammer HK22 Cohesion Solid Reactive

Hammer built the Special Effect for a strong, early asymmetric read on medium to heavy oil. Specifically, the asymmetric Huntsman Core posts a 2.470 RG, a strong .050 differential, and a .017 intermediate differential, numbers that produce high flare and a defined breakpoint, while the HK22 Cohesion Solid cover at a 1500-grit finish reads the midlane early and drives through the pins. As a result, it gives you strong, early traction with a continuous backend. The per-weight specifications are listed below.

A Strong Asymmetric Core for Flare and a Defined Breakpoint

At the heart of the Special Effect is the asymmetric Huntsman Core. At 15 lb it measures a 2.470 RG, a strong .050 differential, and a .017 intermediate differential, a combination that produces high track flare and a defined, asymmetric breakpoint. The low RG gets the ball revving early while the strong differential clears oil.

Because the Huntsman core is asymmetric, layout has a strong influence on the reaction, so your pro shop can tune the pin and intermediate differential to control how early and how strong the Special Effect plays. That tunable power is shared across the Effect line.

An HK22 Cohesion Solid That Reads the Midlane Early

The Special Effect wraps that core in Hammer’s HK22 Cohesion Solid Reactive coverstock at a 1500-grit finish with factory compound. The Cohesion solid reads the midlane early with strong traction, so the ball gets into a roll on medium to heavy oil and drives continuously through the pins.

That early, traction-first read paired with the strong Huntsman core is what makes the Special Effect a dependable heavy-oil benchmark. Leave it at the box finish for medium to heavy oil, take the surface lower for more traction on the heaviest volume, or polish it up for a cleaner, longer look as the lanes dry.
