One crucial aspect of managing steel shot pattern is selecting the right wad. Shotshell reloading necessitates the use of wads. They cram extra space into the shell to ensure that the shot and steel Shot powder don’t move. They also serve as a barrier between the powder and shot charges, protecting the shot from hot gasses and sealing gasses behind the shot so that it can be driven down the barrel. The wad also serves as a twofold barrier, protecting both the barrel and the soft shot from harm caused by contact with the hard barrel steel
The CSD 114 wads were developed primarily for reducing felt recoil.
