Bullet length and shape will also play a role to whether or not a loaded round will plunk

Absolutely. I can load pointy-profile round nose bullets like Berry's plated round nose a LOT longer than relatively squat JHPs like Montana Gold because the point where the Berry's shrink to less than full caliber diameter is a LOT farther from the nose of the bullet.
A word of caution for those doing the plunk test. I have seen multiple examples of factory and hand loads that will plunk fine in one chamber and bottom out in another. I would recommend a case gage to be certain. For example, my P30 chamber will pass most rounds as they seem to be generous. My P2000sk has a shorter chamber length, and longer give bullets tend to engage the rifling sooner. The Glock examples I have handled, failed more rounds than my various P30s. A good reminder to case gage the important rounds.

Certain of what? I've seen rounds pass a case gauge and fail in my P99's chamber because they were within SAAMI spec but the bullet shape + overall length put the bullet into the rifling before the round was fully seated in the chamber. The chamber of the gun a given round will be shot in is the only gauge that is truly meaningful.
Yes, and it didn't make much sense with your assertion that using a case gauge would make you "certain."
No. As stated earlier in the thread, I have determined which of my pistols has the tightest chamber, and I use that one to gauge rounds.Do you actually separate rounds based on the intended pistol?
