It can get confusing for sure. For years I used Bullseye for everything, then a boat load of new powders started to appear. A little experimenting and you will find the one's you like. For manuals I like Lyman 49 and Speer and of course the powder mfg. web site. Handloads.com is also a good reference guide. As mentioned before, read the entire manual, not just the "recipes". Lots of useful info there. Any guide is better than no guide and to me the more the better. Compare. Good luck!
