I recall you testing 9mm's where I think you found considerable improvements in segregating by case length. That is, if my remember-er is working. Did you also segregate by headstamp? The question came up the other day but I couldn't pull up enough details to help.

Thanks!

I did by overall length.
And it was in a Colt Commander, which could make a difference. It should be tried in other makes of the 9em em because it may not hold true. Quien sabe?

Yep, understood. I'll go reread in a bit. Thank you!
