Speed limit for general purpose vehicles
The Walker Wad Wizard was designed to "retard" the wad at the muzzle. The Black Cloud shotshell has a differently designed wad, sot of like speed brakes on the rear of the wad, to cause IT to slow in flight, releasing shot. Combining the two may not be a good idea.
