First of all, I use magnum primers in all of my rifle loads. I have found the Federal GM210M, Large Rifle Magnum primers to be reliable and in my case readily available. With magnum primers, especially when starting to work up a load from scratch I have found that there is no difference, It also simplifies which primer to use without going broke buying a primer for this and a primer for that. I have also used Winchester and CCI primers with great success.
I have been reloading since 1972 and while having used Lyman and Redding equipment have pretty much gone to RCBS for all of my loading equipment, RCBS makes high-quality equipment at a reasonable price and backs it up with, so far over the years, a 100% warranty. If something breaks or doesn't work quite right, call them and it will be replaced on the spot.
As for manuals, I use a variety of manuals based on the type of bullet being loaded. For a how to do it manual, The ABCs of Reloading is a good guide, As well as the Hornady Handbook of Cartridge Reloading. Since most of my reloading is done with either Sierra or Nosler bullets, I use the Nosler 9 and Sierra 6th edition manuals. I have found it best to use the reloading manual for whatever bullet you are planning to shoot.
Good Luck and Have Fun.
