Best place to get all of what you need
I would recommend getting a single stage reloading kit
from the big names like RCBS, Redding, Forster or Lee.
Some of the kits come with a reloading manual as part of the deal but if not then buy a reloading manual from one of the bullet or powder manufacturers like Nosler, Sierra, Barnes, Speer, Hodgdon, Alliant, IMR etc. Once you get the book read the front pages which is usually an explanation of the reloading methods. Then they have the load data
for each caliber which will give the miminum and maximum loads per bullet weight and caliber, live by it for awhile.
You can also go to any of the Carter Country gun stores in Houston and they will have the most reloading stuff. Another is 10 Ring in NW Houston on Jones Road. Academy, Gander Mtn or Bass Pro don't have much. You will need a few other items to get started like dies for your caliber and a caliper, you can get either on-line or at the stores. Don't know about Bay City but there may be a store out your way with some stuff.
If you want to go basic to begin with then Lee makes some great stuff at a reasonable price. RCBS makes everything and they will stand behind their products 100%. Forster and Redding are considered to be top of the line in most cases.
You can also go to other sites to read and do searches on topics you have a question about (just ignore the egos and pi$$ing contests)
(good site for beginners)
(another good site for beginners)
(some bad-mojo but mostly helpful posters)
(probably the oldest and largest site with the most egos)
(most knowledgeable and detailed but some of the posts will go way over your head until you have a lot of reloading behind you)
