If you are using these in an AR platform rifle, stray away from Federal primers as they are softer and slam fires may result. I use CCI 450 primers with ball powders like H335 or H322, it helps with load consistency.
Get at least 1 load manual. I like the Lyman 49th, but each bullet company prints one and so do the powder companies. I like Hodgdon's paperback manual. You can find it at the news stand.
Bullets are tough to find, but they can be had. I use Hornady FMJ bullets, Sierra and these from Everglades

Be aware that loads listed in the manuals will be for specific length barrels, so if yours is shorter, you will not see the velocities they list. A 16" carbine will be upwards od 200 fps slower than the listed velocities.
