Ammo temp higher maybe?
My first chrono was the Magneto Speed, but from what I remember one of the advantages of it over an optical array is the lack of environmental "interference" associated with the conventional chronos.
I was starting to see some variance in velocities with my chrony and thought the same as above "ammo temp". The next time I went out I had my ammo in a cooler to prevent this, and I was seeing anywhere from 50-150 fps differences from 8 am to 2-3PM. I have since switched to the MagnetoSpeed and haven't seen the issue since. I have no idea, for sure, what caused it but from what I could "tell" it had something to do with the lighting. Take it for what it's worth!
Temp sensitive powder? What was the outside temp range from 8am to 2-3pm?
Yes the sun does mess with the Chony brand more than better units as the sensors are high up and get more sun. My first chrono was a Chrony Beta and noticed it and ended up selling it and upgrading. My Oehler sensor is about 1.5" down into the sensor body so it doesn't get effected by the sunlight.
Just know when you need to chrono and do it the same time or use some cardboard and build up around the sensors some.

I use the louvers. I was shooting from shade so my ammo was shaded. I mean one minute the sun is shining and I get a high velocity number. One minute later, the sun is not shining and I get a 80-100fps lower velocity - with the same load - one minute later.
It's gotta be the sun/shade thing from one minute to the next.

Nothing would surprise me about the "features" of the Shooting Chrony line....they're one of the most frustrating bits of kit I've ever owned.
I sold mine and purchased the first gen Magnetospeed....and, the second gen upgraded pickup unit. Other than Magnetospeed's indifference to early adopters and a crap design on the earlier clamping systems, the units have delivered repeatability and are way easier to use than any chronograph I've ever used.

I hate the Shooting Chrony's. They are absolute piles of ass. Get rid of it and spend the bigger money. I was out shooting and using mine, it says "2777, 2777, 2782, 1197, 1254..." and no, the bullets did not just roll out of the barrel and drop on the ground.
I believe Magnetospeed has folks' attention.
