I reloaded a few hundred rounds of 9mm today using my own once-fired brass that I collected over the years. None of my brass is mystery range pick up stuff. Almost all of the brass is Winchester from WWB, with a few other headstamps mixed in.
As I was measuring the COAL on some random rounds, I felt the bullet on one of the rounds slide into the case. The bullet bottomed out on the powder charge. With a little effort, I pulled it out of the case with my fingers. I then tested about a hundred rounds by pushing the bullet end into the wooden workbench and found a total of four rounds with loose bullets that can be pushed all the way to the powder charge with just my finger pressure. Every one of these rounds has the "Speer 9mm Luger" headstamp. These Speer cases are different from the rest of the headstamps because their heads seem to be "cupped". I don't know the significance of this, so this is just an observation at this point.
Out of the 7 rounds with Speer brass found so far, 4 hold the bullet so loosely that I can push it in by squeezing the rounds between two fingers.
The bullet is a Winchester 115-grain FMJ FB and all the bullets I pulled out with my fingers measured correctly, .3555 (The digital calipers are accurate to .0005)
The brass came from my friend's factory-new Speer ammo used a couple of months ago. I remember finding some of my friends .45ACP brass from his "Blazer Brass" ammo with the same "cupped" case head. Now this Speer brass is mixed into a few thousand of my cases... Obviously, I now have to sift through all my brass to pull out the Speers.
None of the mixed headstamp rounds I tested so far have had any signs of bullet setback other than this Speer brass.
Has anyone else experienced this problem with Speer brass? Did I just dodge a bullet by avoiding a kB?
