The same problem cropping up with different projectiles, different firearms, different propellants. But the problem cropped up with brass (of different chamberings) bought from the same seller? Suspect the brass. Or the scale. Or the loader.
Put a REALLY ACCURATE micrometer on the brass, bullets, everything, before and after loading. Double check the scale.
Do you have access to a chronograph? Are velocities off from expected?
Good luck. Keep us posted, please. And please tell us the firearms used. Do you have any other firearms you could try these in? (But don't ask to borrow mine.
)
