It’s more than an explosion or an eruption; it’s the new Columbia 300 Kaboom! Columbia 300 is looking to make Kaboom a household name for bowlers who need excellent length and strong backend without breaking the bank. The engine behind the Kaboom is the new Detonate core. Its symmetric shape is extremely unique, and there isn’t anything like it! The Kaboom also gets its easy length and backend from HK22 with Reflex Pearl, the most booming cover base in bowling, and this version produces devastating results. Medium oil and lanes that are breaking down are no match for this explosive release.
