RE: Getting in the game
Most if not all reloading presses will handle all the cartridges. But the one thing that has not been memtioned is you will need to purchase a die set for each and every cartridge you will be loading. And the range you are talking about will set you back a bunch of bucks. But as most the others have said, start with one, study and learn your A,B,C's. When you finally getting familiar with one, then go on. And, then there is the firearm to use these reloads in. And on, and on, etc.
