Large Volume brass qualifying is MIND NUMBING work!
Anything you can do to speed things up on large volumes is a good idea.
Nothing is quite as fallible as the human eye after about 1,000 rounds...
I do TONS of rifle brass...
Case feeder often sorts out the .308 brass from 5.56 brass, the .308 simply stays in the feeder bin, too long for the drop slot.
(Same with .30-06 brass in .308 buckets)
A case neck qualifier sorts .204 & bent necks/mouth brass from the 5.56 brass.
Neck qualifier simply pushes a 'Die' into the case mouth via electric solenoid,
Small enough to fit into a round 5.56 mouth, punches bent or .204 out the bottom.
Bent necks won't center and punch out the bottom.
Rolling cases (Case Pro machine) will make cracked handgun cases 'Chirp' like a bird keeping you from the blinding work of inspecting loaded rounds for cracks which often aren't obvious before a bullet expands the crack.
(Case Pro Roller also takes the 'Bump' from feed ramps out of the cases so they feed flawlessly)
I like the idea of a 'Cigar' box bottom!
On a declined table with shaker that would run cases past you in volume making identification MUCH easier...
The width of round bottom groove would alert you to over width cases even if they were very close in diameter...
OK, brain has ANOTHER idea I don't have time for, but probably won't let me alone until I try it!
