Why should I have to develop another load just because speer used the wrong primer?   
 I also run them on a progressive, so it sucks when you go to prime and it just mashes the primer.  After the first 20, I sorted the bag before dumping them into the case hopper and found the rest.
If it was my range finds, then I would be a little bummed, but I paid for these and 10% of the bag is unusable for my purposes.  I did get a lot of nickel federal cases, so it wasn't all bad.  I use those for hunting/carry ammo when I have them. 
I know lots of people prefer the small primers because it fits with their other calibers they reload - I only care about all my brass matching for the caliber.  If I'm working on uber accuracy loads, then I match lot numbers or weigh cases, but for everything else I just want uniformity in parts.
