I've noticed that on several (really used) used guns I've picked up that often as not the chamber mouths are smaller than the groove diameter of the barrel which has never made much sense to me.
This was so on the 62 Police, Navy Arms ( made by Uberti)I picked up a couple years back.
Accuracy was so-so at 25 yards with .375 balls so I finally reamed out the cylinder mouths to .379 and have yet to try it out with .380 diameter balls cast up.
I'll get to it one of these days and post the results.
Any way, I have noticed this inversion of chamber mouth to groove diameter several times in various makes of reproduction guns and am curious about the reasoning.
