HEY! Jetblueshooter!!
We aren't born knowing this stuff! I started loading when I was about 16. No Dad or other mentor around.I'm 68 now,haven't blown anything up.
We all start by wandering a path. At least you think!! And you ask questions,AND,you are willing to learn !! Thats good.
Fortunately,as has been mentioned,there is no need to re-invent the wheel.
The manufacturers of reloading components have a serious interest in your safety and success. They make really good reloading manuals.
I have not used them all. I've seen the Lyman and Lee's ABC's of Reloading recommended.I never tried those.I'm sure they are great!! Seriously study the process of reloading.
Myself? I like having the handbook of my primary powder supplier. That would be Hogdon.
I also like to have the handbook of my bullet manufacturer. I use Nosler,Sierra,and Hornady. Yes,I've used Speer,and someplace I have an old one of those.
The bullet specific ones give tested data that works with the bullet you bought from them.
All of the manuals walk you through safe reloading process.
Hogdon emphasizes powder. They sell a magazine format annual that is useful.It has new powders in it.
Lyman has a cast bullet handbook,I believe.
The component outfits have websites. Hogdon offers load data,Hornady offer an easy ballistic software,etc.
I will leave you with one Gold Nugget.
The most likely way to wreck a gun and get hurt badly is to load a double charge of powder,or load the wrong powder.
Just my opinion here,but powders like Bullseye are high energy and they don't take up much space. Don't get me wrong,they are economical and they often perform very well, but I like a charge that fills the case enough that when I visually check my powder levels before I seat bullets,a double charge at least catches my eye.
If you ever load a rifle case up with a rifle charge weight of pistol or shotgun powder,you will wreck a gun and probably get hurt.
It is imperative you have routines that you follow every time,with redundancies to make sure that never happens.
Only one powder on the bench.Period. If you find unidentified powder in your powder measure hopper,don't guess. Its fine lawn fertilizer!
Check your load book carefully! 4198 is not 4895!! Then read the label on your powder. Twice. Your brain will be more engaged if you read it aloud. Might seem silly,but that as SOP in a Chemistry lab I was in once.
OK,enough. Welcome!
