For those who did not say, were you mentored, or did you stumble through the learning curve on your own? In my case, I had outside influences help me learn. My father was not a reloader. He was good at many things, but wasn't mechanically inclined.
Nobody took me shooting and absolutely no interest in what I was doing. Learned it all from books and magazines. Didn’t shoot a real rifle until I bought my own when 18.
Been a long learning curve since 1979, and still learning!
