There is plenty of 40 brass allover the place and if you pick up brass the RSO is watching and if you pick up too much brass you get bitch bites all over your back before you can stand up. Will go and shoot and catch all brass and check it monday to check this out, maybe this is like childbirth and the pain of decaping a shit load of brass just kind of faded away. I shoot and reload a lot.

And I only picked up 30% at best

Most were shot at an indoor range with all kinds a assholes around and brass everywhere.

I don't know I have been letting them pile up, you do kind of go into a trance after a while depriming. Maybe age is creaping up on me but I think I would remember depriming 1000 rds. Anyway I'm going go to the range and shoot 50 rd. thru the Glock barrels and the KKM barrels and check them all.

I just picked it up and put in bag for later and now i'm trying to figure it out.

Primers are just gone, this was factory ammo. just went thu it all and 100% of DT and Underwood has misiing primers and about 75 ppu out of a gallon ziploc bag had the primers still there.

I have a Glock 20 and a 40 MOS, shortly after I bought them I realized the brass was bulging at the bottom and bought KKM barrels for both of them. Shot both a lot but mainly the 40 with a mixture of mostly PPU with some Underwood and Double Tap.
So the other day I got out the huge bags of brass to start decaping pryor to cleaning and realized that the primers were missing in about 80% of the cases, the primers that were  still there seemed perfictly normal.
So I took a small ball guage and miced the grove dia. and the stock Glock barrels were .4015 and the KKM were .3998, I don't have any way gauge the land dia. other than turn down a plug or something.       Any ideas or thoughts ?

So everyone in DC hates/is scared of Trump, that really makes me like him.
