The Fallout is a very strong symmetrical ball from Hammer. It takes the HK22C2 Solid coverstock from the Zero Mercy Solid and pairs it with a new symmetrical core shape. The Aftermath core is a higher RG (2.520″) design with a high differential (0.052″), intended to keep the very aggressive shell from making the ball burn up before it gets to the pins. The highly aggressive cover is finished with 500/2000 SiaAir, making it extremely strong and early. Bowlers looking for a symmetrical option on longer and heavier oil patterns will want to give this ball a look. We needed a lot of oil in the front of the lane for this ball to be at its best. The slicker the pattern, the better the reaction was for us with the Fallout.

Stroker

Stroker loved the hook, traction, and continuation that he saw from the Fallout on the heavy oil test pattern. He was shocked when his first few shots crossed over the headpin from where he usually lines up. He moved farther left to open his angles and saw the ball finish right in the pocket. He loved how strongly the Fallout drove through the pocket on this pattern for him. He didn’t have to reduce his speed or hit it harder at the release to get it to shape on this condition. He was able to keep moving left with his laydown point in transition, opening his angles, and the ball got back to the pocket shot after shot. When the Zero Mercy Solid started getting a bit too forward, this ball was an excellent option for him. He didn’t need to change the surface or wipe down the
