I just bought the Lee Loadmaster with 9mm dies. Im new to this also. I am used to setting up multi operation machinery for the last 20 years so I think that will help. After all you are just pulling specs and making each step match the book. I plan to buy other calibers as time goes on and maybe even a mec shotgun press in the future. For the time being I felt it was best to make the smallest investment for the caliber I shoot most often. I went and purchased a Lyman manual locally so I had some reading leading up to the arrival of my press. This really isn't that hard, its just that the repercussions of a mistake can cause serious injury. Good luck and let us know how your setup works out.
