So, after 10 years plus of loading, my 12 gauge SL900 Dillon showed a problem with inserting wads into the hulls. Close inspection revealed enough wear in the wad guide sleeve and the wad guide to let the wad catch the edge of the shell mouth. I just called Dillon and spoke to Gary in parts. They are sending out a complete wad guide swing arm assembly ($34.95 on the website) on warranty. I'm impressed.
