I can't see how a one piece base can help with the ejection issue. It will, however, allow you to mount about anything on the gun. It helps to have easier access to the chamber with anything, one piece bases hinder that. The EGW is a fine base (although expensive for what it is), but to keep the shells, fired or not, from hitting the base and not fully ejecting, a two piece base is a better choice. Obviously some folks have no issue for whatever reason. This is how I worked on the problem that I was having.
