Hi Mathman,

To elaborate a bit on my earlier answer, fired brass all allow a .284 bullet to slip easily into and fall through the neck, except this one.

I was a bit careless in initial reforming by allowing the lube, Imperial Sizing Die Wax, to get on the shoulders of a few pieces of brass. This resulted in dimpled shoulders in those cases. I have seen the same happen before a few times when reforming other cartridges that required moving the shoulder back. All the cases reformed without any lube on the shoulders formed properly.

Loaded and fired this one particular case twice to see what the consequence would be, and as expected the neck is distorted enough by the dimple that a bullet will not slide past the shoulder/neck junction. Oddly, there was very little resistance in chambering or extracting the loaded round.
