Maybe this wisdom also applies to chronographs?
For muzzle velocity purposes only, you may be right.
For the purposes of testing a ballistic coeffiecient, the only way to beat 2 chronies may be the ohler acoustic set up and definatley doppler radar. Other than that, a cheap, easy way to get you a number to get started at LR is to shoot through double chronies.
