I read two manuals before I ever bought a jug of powder. I was also scared chitless the first couple of times I pulled the trigger on reloads.

It took a long time to become comfortable with doing it. The ABSOLUTE best thing I ever did was to buy QUICKLOAD. I can look at it and run calculations and actually see roughly what the pressures are. This has given me more confidence in my loads.

Also develop a process that works for you. For example I don't throw but one powder charge at a time, then seat the bullet, while others may throw 20 charges then load 20 bullets. There's no right or wrong but how ever you do it make sure that you implement it EVERY time.
