Roger's comment from the previous Glock post notes that:
When a case has a Glock bulge, it will commonly chamber almost all the way in, stopping a few thousandths of an inch before full chambering.
This can and does cause the barrel to fail to go up completely into battery,
This commonly causes misfires and off center (low) primer strikes because the case / barrel are not all the way up in full battery and alignment with the firing pin.
Some resizers don't reach that far down the case, so Lee sells a kit called the Bulge Buster which consists of an elevated brass pusher and a small bin to catch the resized brass. You need the Lee final crimp die in your caliber with the internal bits removed for this.
Or if you have the die, remove the internals, put an improvised pusher made from an old steel .223 brass with an old 9mm steel brass on top,
a small plastic tub with a 7/8" hole will catch the brass as it pops through the die.
This brass had already been decapped and sized so this operation addressed only the bulge. There was a great variation in bulge amount from one to the next with most brass passing through the die and staying above the smallest diameter. I did have one that seemed to have no bulge at all that came back out the bottom having encountered no resistance at all going up.
I tested this batch in my barrel and found them all to drop fully down with no resistance. NOTE: This trick will NOT work on loaded cartridges. Drat! Remember to lube the cases before resizing.
