Uh...A chronograph is indespensible to any serious reloader. Velocity equals pressure, if you're seeing a lot more velocity( At least 50fps more) than the manual says you should at that charge-weight, you're at max pressure for YOUR gun. No two guns are the same, no two will show the same velocity or, even close to the same velocity with any given load.
