I like the Lymann manuals, they have alot of bullets. When I reload Noslers I get data from their site. I like they tell you what is most accurate in their test gun. Might not be yours. But good place to start. Lymann also tells you must accurate. I like that, for a starting point. Get that powder to start with.
For rifle I started 30-06, IMR4350 is very common powder, it maybe for 308 too. So I started with that. I have bought others since then to tinker..
I'd get digital calipers. Powder trickler is nice. I like Lee lube. Get a couple loading trays. Take good notes. Write down on paper/computer what you did and on the box of ammo put info.
Some manuals say not to size new brass. I have found dinged mouths, so I do. I also bought a tumbler to get resizing lube off. It is not good for primers.
I like hand priming. Can inspect, make sure not upside down and flat. Careful handling primers, don't get anything on them. You can dump them into hand loader tray. I have Lee, but there are others.
I have both Lymann digital and RCBS 5005 balance beam scale. Some people don't trust digital. I bought check weights to check mine. I would not use a nickel. I leave it plugged in, and off, some say that is good.
I have RCBS powder dispenser. I clamp it on a table with big C-clamp. Only one powder in room.
Lots of press, probably all good. I like my Lee, 4 hole turret. I buy turrets for all the rounds I use, so I don't have to keep setting up.
I have lots of manuals with lots of powders. So I can find what I am loading. I also like reading them. I have Hornady too, I load Hornady. I have Speer, I like the info. I like readying about various cartridges.
Hogdon has a website with info too. Others do too. Just happens they have powders I tend to use.
Pay attention to seating depth. Manuals will use less powder if shorter round. More pressure when seated deeper. Copper or lead makes a difference, find your bullet. Lead slides easier less pressure. This is more for handguns or 45-70.
I wish I had forums for my dumb questions when I started out. The manuals don't always have what is basic to them. It stalled me for years.
