I plan to get a press for 20 guage and start doing those after I get my other press set up and going. I want to start loading my one on them since the shells I like to use for pest controle (coons and such around the chicken house or rabbits) is the 3" magnum goose loads with #2 or #4 steel shot and around here you can only get them for a small part of the year and then they are over $10 per box at best.
I like to reload light loads of #8 in AA hulls for quail, which is what I'm shooting at about 90% of the time. Don't know that it's that much more economical, but I enjoy it. For other loads, I shot them so seldom I just buy the factory loads.
