OK, got it figured out and the gun is running well.
I ended up working up drill bit sizes from a #45 to a #44, and finally with the #43. The #45 gave me extractions (basically dropping them at my feet), but FTF. The #44 gave me about a four foot ejection pattern with intermittent (1/2 the time) FTF. The #43 gave the gun an 8-9 foot ejection without any malfunctions whatsoever through 120ish rounds. It was funny how going from the #44 to the #43 almost doubled the distance the cases were being thrown. I'm sure someone who's good at math could explain area of a circle when the diameter is increased by 0.004" combined with spring tension and barrel pressure. I know I can't. I'm just glad she's running again.
I hope this helps someone.
