[QUOTE="Pdvdh, post: 415709, member: 4191"] [b]Re: Single Unit Chronograph Data Uncertainty[/b] It gets even more tenuous. My opinion is that a minimum of two readings are required from each bullet fired - if you really desire confidence in your chronograph data. The Oehler 35P provides that with its Proof channel. Other than one chrono unit with a proof channel like the Oehler 35P, you really need to be running two chrono units in tandem to establish the validity of the data you obtain. I've posted this opinion and provided the associated details and rationale in several other prior threads over the past year or two. A fella has no means of corroborating the validity of one MV spit out by one chronograph. A second reading is required. If you ever begin running two in tandem, you'll see the occasional blooper data cropping up, and realize that depending on a single chronograph for any serious ballistic predictions is, at the minimum, periodically misleading.
