I know that you'll need 2 presses 1 for the 50 BMG and one for all the rest
The size of the dies and the round for the 50 are too big for the standard press I think RCBS makes a 50 BMG press
For everything else, get a Dillon press, preferably a 650 but a 550 is more than adequate
Books I use are the Lyman reloading Manual and Any Shot You Want by A-Squared with Lyman as my "Bible"
Depending on the volumes you want to load you can spend a lot of money, and 50's use an awful lot of powder--buy it in 8 lb kegs
re: The Dillon--It is not cheap, but IMHO they are the best you can get, with a no hassle lifetime warranty(life of the machine--your grandson could send it back for repairs and they'd do it free) on all of their machines and just about everyone who owns a Dillon has great things to say about them and their customer service.
Theres lots of good gear out there and lots of info
Good luck with whatever you choose
