I'm a long time fan of RL22 because it is a good slow burning powder that offers plenty of room to go up and down with your powder charge.
So far as needed loading tools, I think the bare minimum to safely begin your new hobby is a case trimmer, Lee offers an inexpensive one that trims to length and will work off your drill. You need a dial caliper, a decent scale, ream and chamfer, primer pocket cleaning tool, case lube, powder funnel, loading tray. I don't know what method you planon using to measure and drop your powder charges so it's difficult for me to offer help in that area. I individually weigh each charge and manually drop it in the funnel. If this is how you plan to work you'll appreciate a powder scoop kit. If not others will have plenty of options to suggest. I also think a bullet comparator is important to have, and is a tool you'll appreciate throughout the years. I don't personally use mine very often, but that is just me. I almost forgot one of the most important items, one or several good hand loading books.
Welcome to THR and enjoy your new found hobby!
