Is there an adjustment to get more "bell" on the case during the deprime stage? It's not quite flaring enough to get a wad in easily.
There should be no problem inserting a wad IF
you have the wad fingers in the wad guide. They are made out of a tough plastic, made to push the mouth of the hull more open to prevent the wad from catching on the crimp. In the past, they were made of brass.
