The 4 die set that includes the factory crimp die will be handy for the 9mm and the .40 S&W. The fourth die can save grief when you find your rounds will not chamber smoothly. I never found a need for it on the rifle calibers I reload.
(.223 .22-250 .308 .30-06 and .223 WSSM) I also use a three die set for the revolver calibers I reload. I like the Lee Auto Prime, it lets you prime your cases in front of the TV set.
I cant speak for the pistol calibers, as I have no experience reloading them. For the rifle calibers however I would get the Lee 3 set deluxe. The only exception is if any of the rifle rounds are for a semi-auto, because neck sizing for a semi-auto is generally a bad idea and a crimp die would be more useful.
Though I don't crimp for my AR15.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
