RK, it sounds as if your cases aren't being sized properly in the web area OR the forward part of the case isn't being reduced to a diameter that will allow it to chamber completely. I often use the barrel from the pistol I'll be using the cartridges in and drop them one at a time into the chamber to see how well they fit. I also keep a spare barrel around for some cartridges just for that purpose.
The dropping firing pin retainer plate (also locks the extractor in place) could be a too-thin plate, a weak firing pin spring, a too short or bent firing pin or a combination of the above.
