The following components are incompatible with older versions of CVA ammunition: Powerbelts, roundballs, sabots, and even some sabots. The redesigned CVA Lead Round Ball Powerbelt (Right Hand) is one of the most popular reloading products of all time. These bullets are machined a few thousand ultra precisely to have the thin copper plating that reduces bore friction allowing for higher velocities while still allowing for optimal bullet expansion within the rifling grooves. One of the most popular is the Powerbelt A second generation which is copper plated and pre-lubricated to prevent lead migration and under-sizing. This bullet package is perfect for those who want to try a copper plated hard bullet. Due to the coating process, pinholes in the copper are very small. As a result, these bullets do not show up on most reloader's "Best of the Best" lists. For those who enjoy the challenge of competing against lead, the CVA Round, Belt, and Dirt Slinger may be just the bullets for you!
