You should ALWAYS use a reliable chronograph to measure even factory ammunition. I will also add, I will share an article on chronographs here soon. Don't waste your time with cheap/inaccurate chronographs. The best one currently I have found is the new Garmin C1. Seconded by Labradar and Magnetospeed.
