Flattest shooting database

[Greatgrandad]

I have a 30 inch 300 RUM, and a new "club" where I can actually shoot it for the first time in about 6 years. I relocated about 2000 miles and the "club" is newish. It would be a hoot to see how fast I can make it go. It's bench rest setup and it never occurred to me to give "speed" a go with it.

Elevation would have to be another thing to standardize on. DA, density altitude, effects actual trajectory significantly but if allowed to be manipulated... That is why submissions would need some validation.

If you wish to see something really fast -
300 RUM, 30-06 and 308 with sabot 22 caliber loads. The 300 RUM 52 grain has broken 5,300 fps and the 30-06 52 grain has broken 5,000 fps.

Anyone know of a chronograph that can do muzzle velocity and velocity at a 300 yard target?

LabRadar? Garmin?

I was just looking at them on E Arthur Brown. $15.95 for the sabots, $15.95 for the seater and $16.95 for the case mouth expander. Though I can make one of those on my lathe. All in all, cheap for such an experiment.

It doesn't have to be me to get valid numbers and that's not the point of the project.
