Hammer Zero Mercy Tour Bowling Ball Review

The Zero Mercy Tour is the first ball in the Zero Mercy line to use a different core shape. Instead of the Super Offset weight block used on the Pearl, Solid, and Hybrid, the Tour uses the Obsession Tour asymmetrical weight block. This core design has a much lower RG (2.469″) compared to the 2.524″ RG in the Super Offset design. The differential is also much lower at 0.034″, compared to the 0.053″ offered in the other Zero Mercy releases. This core has been used before in the Obsession Tour and Envy Tour, as well as the pearl versions of those bowling balls. The coverstock on this ball is new as well. This is the first “Tour” ball from Hammer to use HK22C2. Its new C2 Tour Edition coverstock comes out of the box at a very rough 500/1000 SiaAir finish. Between the quick-revving core shape and the very dull box finish, the Zero Mercy Tour gets started early and is very controllable downlane. As smooth as the ball was downlane, we still had plenty of continuation through the pin deck. This ball was at its best for all three of our bowlers when there was more oil in the front, but they were still able to maintain decent pin carry throughout our test sessions with the box finish.

The dull surface tore up the front of the lane pretty quickly and
