Gopherfan,
Check out the Variflame system. I use it and it is really sweet and easy to use...here is a link to Cabelas and what it is.

Best of all I don't need to use the Lee auto prime and I load the cups at the bench as I wait for my gun to cool between shots.
PS.
Just found this link to a test on the Variflame.
