What Winchester-1897 said! Be aware that depending which area you reside in, bullets suitable for .303 are not too easy to come by and neither is powder. I bought the Lyman Reloading Handbook and I love it. For the beginner, it takes you through every aspect of reloading from tools and equipment, to prep, to set-up, and finally to finished ammunition. There may be other manuals as good, but personally I don't know of one better. I also have a Nosler manual, but that only gives specs for their bullets, for example. All the bullet and powder manufacturers have spec sheets available on their sites so the internet is truly your friend. If you're local, we could meet and chat. If not, there may be some gunnutz in your neck of the woods who would be willing to sit down with a newbie and show you the ropes. Good luck to you, whichever route you choose to go.
