If am helping a friend get started in reloading. He has a 223 (which I know we'll) and a 270, which I have never loaded. He has dies, lots of once fired brass, and some bullets. What is the go to powder? I am just thing 3006 powders. 4350? 4064? What would be the one powder for him to buy? I can hook him up with primers.

Thanks for tips, Tim
