It is not complicated unless you make it that way. I have >70 hours of math,physics and chemistry and do not care. Loading,shooting and hunting is what I care about. Sure, my understanding of the disciplines help a lot. But I am not in the business of ballistics, OR teaching it, OR trying to impress people with it.
Use what you know and make it work. Have a good time doing it.
Enjoy it. Now that is not rocket science.
Sometimes people have to come full circle in life!
