Handloading is somewhat like climbing a ladder.
You gotta start at the bottom and work your way up - slowly! You can't get to the roof without putting your foot on each rung, BUT you can leave the roof without touching the ladder! Not a good choice!
Stay safe, go slow, keep careful, meaningfull records (like a journal), read, listen, observe, and analyze everything you do, and everytime you shoot. Your weapon will talk to you if you listen, and your targets will, also. It's a fun ride, and doesn't have to be tedious or frustrating, though sometimes it seems to be.
You may discover something different from the experiences of others - that's ok. All barrels are different and respond to ammunition differently. The various load charts may seem overwhelming as the data is somewhat different from chart to chart. That's ok, too. It's merely a reflection of the fact that all barrels are different and will give different results from the same ammunition. Don't sweat it. Get on the ladder. Hit that first rung and get comfortable with it before climbing to the second rung and so on. It is not a race to get to the top of the ladder. We are all on the ladder somewhere. Some higher than others, but I don't believe anyone ever gets to the top.
I have found over the last 40 years that there is always something new to discover or some new theory that warrants checking into. You will also find that everyone does not share the same experience or the same opinion of particular calibers or bullets. It's like Fords and Chevrolets. Crap to some is treasure to others. Welcome aboard and fire away! The more you learn, the more you will find you want to learn.
