I have learned a lot on forums, from mentors and at the range and learn more every day. A couple things I wish I knew more about in the beginning were:
1. Holding down the press handle when resizing for a few seconds to let the brass resize with less springback
2. understood the difference between focus and parallax
3. used annealing (correctly) with comparators to see what the resizing was actually doing to my brass
4. Understood the poi difference between shooting with different rear supports (bag v rock v fist)
There are many more, but Id love to hear what key points you missed for years that you wish you knew in the beginning. I know I'll learn some new stuff
