Re: Single Unit Chronograph Data Uncertainty
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. And the frequency of 'periodic' can only be determined after you start running two units in tandem.
Velocity was more than 100 FPS less than last week.
I guess what the little blue Chrony is telling me is that there are bullets exiting the barrel and not much more than that.

Exactly and the proof channel is what makes the Oehler 35 soooo good

I have a Chrony and I am very disapointed with it . It has always been iffy . Of late , it doesn't work at all.
