. . . I like the idea of reloading because of the cost per round compared to store bought ammo. It seems to be much cheaper. . . .
Each round you produce will be cheaper than the factory counterpart. A useful overall average number using (eg) Hornady bullets is 40% cheaper. Many popular rounds (eg 230gr FMJRN 45 ACP, 115gr FMJRN 9mm, etc) will yield less savings, others more.
What you *do* with those savings is up to you. If you buy best value equipment, stay away from "toys", and/or use less expensive clad/lead bullets . . . the savings can easily pay back your equipment investment as quick as you can shoot.
But remember you must front the cash for the tools, and for buying bullets, primers, powder, and brass in BULK. And you will likely NEVER reload cheaper if you put a dollar value on your time, or don't have the time for an additional hobby.
OTOH, many of us have found the reloading hobby as fullfilling if not more so than shooting. At the very least it extends the time you are immersed in your firearms hobby. You're also on a learning journey into the science and art connected with firearms. Finally, you get better ammo lol . . . not so significant to most handgun shooters . . . but incredibly rewarding in your rifle groups.
What do I need to know? As a total newbie, what reloading presses or kits will do what I need without breaking the bank? Where do you get brass, powder, projectile, primers, etc at good prices to make reloading worth it? What about learning, books, etc? Thanks for the help.
You are too early in the curve to have use for answers to all these questions except the last.
Go to the Lee, Lyman, Hornady, RCBS, and Dillon websites. Some of them have reloading tutorials and videos. Watch/read the tutorials. Get the names of some presses and go to Youtube. Look for reloading videos using those press names. See what each does, how it does the work . . . and for many Youtube videos ignore the advice lol. Just watch the operations. Pictures are incredibly more valuable than words.
When you know what single stage, turret, and progressive mean in use . . . come back and talk to us about presses etc. We'll be glad to help . . . maybe more than you want lol.
