I watched Benchrest shooter do it without knowing
They tossed the case in the trash
But why not do both

Curious, do you shoot any, but specifically the cases that are different a second time for verification?
I don’t have the bubble problem
Or case lingth
I made a tool that forces the air out along with check the volume off the shoulder so it is the same
I will ship you a prototype Crude but worksYou’re way ahead of me!!!
You’re the Man!I will ship you a prototype Crude but works
Here’s another thought...Instead of sorting by H20, I use my labradar to sort my brass. For the Nationals I took 100 cases, loaded them as identically as possible and checked the velocity with the labradar.
With a clean barrel I’d fire two shots to foul the barrel and get it up to speed. Then I’d start recording the velocities from the match brass. To keep up with the results I’d just write the velocity on the side of the case. Then sorted accordingly!
If you can zoom in on the cases on the table you can see the velocities on the side.

The first thing you do in making a race motor is to make the cylinder head have the same volume on each. Cylinder
You cc them
Being a old racer I felt the the cases
Needs. To be done
But when trying I found the the bubble and the wet case we giving faults errors
So I made a tool that reduced the errors
I feel a case should be fired two times in the same chamber
U can leave the primers in or remove them a put the spent primers in bottom side up
The next problem was the amount of bubble oh the neck and the varence in neck leingth
So i solved that problem by using the shoulder for the reference area
Trust me it works
Sure anything thing yo can do helps at distanceSounds like great idea! This was a 6BR I only put one fireing on the cases before checking. Dasher, Bra, Grinch definitely need two.
However, I wonder if You could sort the cases while fireforming? It would be interesting to record brass velocities while fire-forming. Then recheck the finished cases again once fully formed. It might be worth a winter time project.
