When you hang out at the range, inquire until you find someone local who is experienced at reloading and see if they are willing to let you learn on their equipment before you get a lot of money into it.

this sticky post at the top of this forum, if you haven't already. The book recommendations are fine. The ABC's of Reloading is now in its 9th edition. Advanced handloading gets you into a whole other area of detail, but most of the specialized advanced techniques are mainly useful in rifle and long-range single-shot handgun reloading, as they make improvements that, for statistical reasons, can be very hard to detect shooting pistols and revolvers handguns.
When it comes to selecting powder, there is a simple approach to use at the beginning and until you get your feet wet. Look through powder company data, like Hodgdon's, that gives measured maximum load pressures. You will notice the maximum pressures listed for different powders are not the same. That may be confusing, but what the powder maker is doing is backing down from the SAAMI Maximum Average Pressure rating by the amount of pressure variation he observed in testing. The lower that maximum pressure, the more variation the maker saw. You generally want to minimize variation where you can, so you make initial choices from among the powders with the highest pressures listed, then read to see if others have liked those powders in your chambering. The last step is important because manufacturer's testing doesn't tell you everything, like how dirty the powder burned or how well it does with powder position changes in the case.
The reason powders with a lot of variation are still listed is for people who already have those powders on hand and who want to avoid the expense of an additional powder and are therefore willing to make do. Since you haven't bought powder yet, pick two or three that have the highest maximum pressures listed and who's load range, from start to finish corresponds to a velocity range you want. Read about them and note which one comes closest to serving your purposes. Commonly, the final choice is simply the one that works well in the largest number of different cartridges you load for. If you can narrow your powder choice like that and test it with a single pound first and find that satisfactory, that makes it easier to swallow buying a larger quantity at one time to get a better price per pound later.
Good luck, and enjoy the new hobby!
