Learning how to properly size a cartrige with proper headspace as the guiding factor. Its OK to sound off to help people, just dont send them in the direction of danger!
So following the directions of the die manufacturer is now Dangerous? Maybe you should contact Redding, Forster, RCBS etc. and tell them that they are sending new inexperience handloaders down the path of destruction and they need to change their instructions before somebody gets hurt or worse.
Just to clarify, I did say the the most precise way is to use a headspace gauge like the Hornady/Stoney Point gauge.
