I'd also suggest Unique powder. Not being as fast as some others (in burn rate/pressure development) you have somewhat more room for error. HOWEVER YOU CAN STILL DOUBLE CHARGE A CASE! Which is true for most pistol powders.

Except for certain special cases, I've come to prefer the plated bullets over the plain lead bullet. You don't show a location, I'd assume there are probably some local shops for powder & primers to avoid hazmat shipping surcharges.

There are a slew of internet providers of bullets & brass. Midway, Berry Bullets, Grafs, Natchez Shooters Supply and the list goes on.
