Apparently I'm seeing this thread a little late!
The guys have given you a lot of great information!
When I began reloading 30 to 35 years ago I opted for a kit but that was before digital scales were invented. There's noting wrong with a beam scale but digital scales are faster, easier to read, and easier to use.
Choose a single stage O-frame press. These are simple to use, very strong, and have withstood the test of time.
Presses
Redding, RCBS, and Hornady are tops in my book and I personally use the Hornady 007 press.
Dies
I've tried most of them over the years and have settled on Redding. I feel Redding offers the very best in design, quality, craftsmanship. If I were to choose another manufacturer it would be RCBS then Hornady.
Hornady bullet seating dies feature a floating in-line sleeve designed to minimize bullet
run-out (misalignment caused by a canted bullet.) The cartridge neck and bullet are aligned in the floating sleeve prior to seating the bullet for in-line, precise bullet
seating. This feature is big in my book as all my Redding competition dies incorporate this feature.
Case Lubricant
Use a spray lube. I use Hornady One-Shot. It's easy to use, works great and it's never failed me.
Powder Scale
As I mentioned above, start off with a digital scale..
Powder Measure
Redding 3BR
Case Trimmer
I prefer the RCBS Trimmer Pro 2 Manual Kit
Vernier
For measuring overall cartridge length, go with a digital pair of these. They're fast, accurate, easy to read, and not very expensive.
Tools
Case neck chamfer/ deburing
Allen wrenches
Screw drivers
Case trays
Priming tool
Reloading Manuals
At least 1 hard copy is absolutely mandatory! My first choice here is Lyman...hands down!
As Marty mentioned, a vibratory tumbler and media is something you should have in order to clean your cases once they've been fired. I have an older Lyman 1200 that still works great. I've recently added a wet tumbler which uses a solution of water and mild detergent along with stainless steel pins. This does a much more thorough job at cleaning, even the primer pockets are spotless!
OH, and don't forget the powder, primers, and tips!!
