The Zero Mercy Solid is part of a rare triple release for Hammer. It joins the Zero Mercy Pearl and the NU 2.0 as three new options for Hammer fans for the winter season. The name is a throwback to the No Mercy series from 2006, while the weight block is a modified version of the High Rev Offset core from the 3-D Offset line. Both Zero Mercy releases use this weight block, with the differences between them coming in their coverstock material and box finishes. The new Super Offset core design has an RG of 2.524″, which is significantly higher compared to the 2.489″ RG of the High Rev Offset core. The intermediate differential is also increased to 0.020″ from 0.008″, with both cores having the same 0.053″ total differential. Both Zero Mercy bowling balls use a new iteration of the HK22 coverstock family called HK22C2. The Zero Mercy Solid comes out of the box at a very dull 500/1500 SiaAir finish. Between the aggressive, dull coverstock and the large-flaring core design, it had no trouble chewing through the oil on our slickest test conditions.

Stroker loved the large amount of hook he saw from the Zero Mercy Solid out of the box on the fresh heavy oil pattern. The ball dug into the lane easily, creating tons of total hook. He was able to start even farther left than he did with his Maximum Effect on this condition. The Zero Mercy Solid retained a good amount of energy for him downlane, with the higher RG core shape helping it retain more axis rotation for the back end. The very dull coverstock had no trouble...
