I've been using a Rockchucker for the past 17 years and as good of a press as it has been, it is starting to get a little sloppy. I am in the market for a new single stage press. The largest cartridge I do right now is a 300 RUM. At some point I will move up, possibly an Edge or similiar. I have been looking at the Redding Ultra Mag and the Forster Co-Ax. What do you guys think?
