If you have a particular brand of bullet that you would like to use, or can easily find locally, I suggest purchasing/borrowing/reading their manual first.
If all you can easily find are Hornady bullets, why buy a Sierra manual?
Hornady, Sierra, Nosler, Speer, Barnes, Lyman, etc. have similar introductions to reloading and will keep you on the right track.
You can always find an older edition on eBay cheap enough and print CURRENT load data from the powder websites listed above. The local library may have material on hand if you wish to go that route.
Personally, I like to use the slower rifle powders for the heavier bullets but I prioritize them by case fill. For me, more case fill is better for ignition. For the lighter bullets I will try the medium burn rate powders first. I think of it like compression in a combustion engine. The more squish you have, the better quench you get, and the higher the volumetric efficiency becomes is my recipe for handloading.
I look in the load manuals to find the range of powders that are called for and compare it to a powder burn rate chart. I start with the slowest powder and see what the case fill is.
If I can find one that looks good on paper (90% fill or more), I load up a few "start loads" and then bump them up in .5 grain increments until I have reached about 1.5 grains under max.
If I find a very accurate load I will load more of those up and test them again. If they don't improve over the 'ladder test' I will either try another powder or settle for the most velocity.
I never load a rifle to max and certainly never start near max. I have found that my primer pockets just don't handle max loads for very long and I don't see the reason for the "dip it in powder and squash a bullet" approach.
Don't forget there are a lot of opinions out there (web), so take what you can from it and make up your own mind. Be safe and shoot straight.
