I might have used up one of the old green Remington boxes (most likely the "dog bone" style box) of ammo in the mix, and if so, it did fine. Did American makers change the powder/charge spec at some point?

I think it depends entirely on the pistol, most likely the mainspring strength.
Weaker spring is more likely to function.

I have no idea if any mfg. changed their loading or not.
