Columbia 300 Dynamic Swing Bowling Ball

We receive more feedback from Columbia 300 consumers about bringing back previous technology and names than any of our brands. It has been a priority of ours to evaluate the cores, covers, and names from the past to make sure we give the Columbia 300 fans what they want. We are excited to introduce the Dynamic Swing, featuring a modified Full Swing core. We have combined this popular core with ERT Hybrid, and left it dull to handle any medium to heavy oil condition. The Dynamic Swing’s medium asym numbers and hybrid cover complements the Authority Solid and original Authority perfectly.
