Often when chronograghing every shot the flyer can be nailed down with a significantly different speed. Cold bore shots for me as a rule were slower. While speed can pick up with a squeaky clean bore.
I weight sort all brass batches and with a couple of rifles used the heavy sorts as a cold bore case and colored the headstamps with a sharpie.
If you put in the colored ones in the magazine last it would be the first chambered and shot in a hunting sitiation. Normally the reduced capacity of the heavier cases would help increase pressure/velocity to help with consistency in the batch.
Chronogragh testing verified the "heavy" case viability in combating the slow cold bore shots.
By tracking velocities & flyers as a general rule all my cases in a batch are labeled/ numbered to further analyze target/velocity strays during case prep and inspections.
Capacity checks after the fact can and might confirm earlier problems.
