Thread: Chronograph advice

Greetings All,
My chronograph is an Oehler 35P that was bought in 1991. It was expensive but I won't need another one. I run a 4 foot screen spacing wihch gives consistent results and the three screens measure velocity twice to alert you to a dud reading. It is still sensitive to light conditions so I pick my days for chronographing, bright overcast being the best. Two of the most important uses for it is validating load data and estimating pressure. If you are getting close to max velocity from the load data then your pressure is likely to be close to max as well.
