Many shooters prefer to use these wads in place of the messier over-ball grease. I wanted to find out what effect if any, they have on load performance. The chronograph results were inconsistent with some loads provider higher velocities with the wonder wads and others lower. There seems to be no difference in accuracy
The wads do reduce or delay barrel fouling build-up when compared to loads with grease over the ball. I wipe the barrel between every cylinder full and find that using the wonder wads materially reduces the effort.
