Blue markingballs are a reliable means of marking a target and are often a good alternative to rubberballs, especially in police training. They are available in our whole range of calibers: .43, .50 and .68. Perfect for all markers with magazine feeding system, because the slicker and more stable outer shell optimizes the feeding out of the magazine into the chamber, thus minimizing the risk of bursts while feeding or in the barrel.
