What the numbers mean
RG 2.510. That is lower than 34% of the 134 current reactive and urethane balls in our table, so it sits on the high side. Storm says "a high RG ball delays its revving, offering more length and angular motion down the lane."
Differential 0.042. Higher than 36% of the balls in our table. Storm says "a low differential ball tends to have a more predictable, controlled motion."
Hybrid reactive cover. Hybrids mix solid and pearl; Storm says they suit bowlers who need a ball "that can adapt to a variety of lane conditions."
USBC allows an RG from 2.447 to 2.813 inches and a differential of at most 0.060 inches (Equipment Specifications Manual, March 2026). Our ball spec table lists every current ball we track, and who makes bowling balls covers which company owns Hammer.
