For a guy just starting out, I'd recommend the Hodgdon Reloading Center:

http://www.hodgdonreloading.com/

It has loads for all Hodgdon, IMR, and Winchester powders. That's a fairly big universe to get started. I've been into reloading for nearly 2 decades, and a rarely stray out that database.

I also recommend sticking with middle-of-the-road powders for the following reasons:

1) Slower powders will get you into trouble in a hurry if you undercharge
2) Faster powders will get you into trouble if you double-charge.
3) Powders like H4895 are not sensitive to where they sit in the case, how much they fill the case or the ambient temperature.



I also want to give a big +1 for Pet Loads. That's a wonderful reference.
