Single Drill Right Hand The Pulse is back in the Columbia 300 lineup. We’ve seen numerous iterations of this nameplate since its initial introduction, including balls with different-colored pins for remakes, and then the offshoot versions of the Impulse balls during Columbia 300’s Hopkinsville, Kentucky days. This Pulse features the new Pulse PowerCOR weight block. The result is an ultra-low RG of 2.468″ and a medium-high differential of 0.045″. The coverstock is a solid HK22-based version of Hyperflex that comes out of the box at a very dull 500/1500 SiaAir finish. Between the solid dull coverstock and the quick-revving core, the Pulse PowerCOR starts very early and is very predictable throughout the entire lane.
