My 2¢...
Speaking not as a reloader (there are other far more knowledgeable people), but purely as an engineer...
If all ammunition is trimmed and gaged, the trimming and gaging is correct, and the ammunition isn't altered (damaged) before use - the dimensions of the ammo should be within specifications. This would tend to point toward the mating dimension, the chamber....
Three thoughts come immediately to mind (not including thoughts of lunch).
•The chamber is slightly undersized and interferes only with ammo on the high side of tolerances.
•The chamber is "tight" and crud-n-such buildup bring it under tolerance.
•The chamber is "tight" and random bits of grit or carbon wedge the cases.
I suppose that go/no-go gages are available for chamber dimensions? That might eliminate or pinpoint a potential variable.
