Great article. Beware though, excessive use of chronographs can cause mental illness. At one time I owned 3 of the darn things...and had them set up to operate simultaneously...because I didn't "like" the numbers I was getting. Imagine, if you will, a proven rifle load, same batch of carefully handloaded ammo, same rifle, same atmospheric conditions within 2%....and getting velocities up to 80 fps different on successive days. Two Oehler's and a Pact. Which verified each other, seldom showing much more than 8 fps variance. Aaaargh. Doctor friend prescribed selling two chronographs and daily infusion of alcohol, flavored with juniper berries. I'm taking it one day at a time.
