Thread: Chronograph advice

A cheap chrono will most likely give you average data anyway.
You could plug in your dope into a ballistic calculator and work back to your velocity.
Working back down from a supersonic crack would also give you an audible starting point for when the load initally goes subsonic.

Disregard the last sentence.
