I started reloading in 1977 and have enjoyed every moment of it. It is a challenge and a science. I suppose almost everyone goes through the "power crazy" phase at some point but, I have discovered that if you varmint hunt consistency is what you are after. You want a tight group with consistent and repeatable data. Buy a good reloading manual and read ALL of the stuff BEFORE you get to the load data. Firearm safety starts at the bench!
When you are doing load development a simple rule will save you time and grief. Take an extra fine sharpie and write on the case the powder and charge, it will come off when you polish the brass. I learned this the hard way, I had all of my loads arranged in a range box in a certain way. On the way to the line I tripped and the box fell and opened scattering the contents. Now I got to pick them all up and go back to the house and pull every single bullet. Wasted time and effort. My granddad always told me "You gotta be smarter than what you are working with." Sound advice.
