So I am just starting to reload. I got all the equipment that I need and am working on setting up my own reloading bench. I have everything I will need except for powder and primers. The calibers that I am interesting in loading for first are 7mm-08, 7mm Rem Mag, and 30-06. I understand that different powders shoot better or worse dependant upon a number of factors with the different calibers. I would like to buy 2 or 3 different powder types and primers to start. Who has any recommendations?
