Dude, you must be above average in intelligence if you're only 16 and you have the foresight and the enterprise to want to take on handloading! I didn't start until I was 28, and I regret that I didn't start much sooner. I had thought about it, but I was always intimidated by the prospect, thinking there was a level of complexity, dedication, and mysticism beyond my capabilities. That couldn't have been farther from the truth.
I know this is going to sound kind of strange, but I swear, taking up handloading has helped me become better at other things in life!
Go for it....you've got one of the best resources right here!
