Howdy Y'all
I have a question on barrel markings
Both are marked 18.2 (16ga) but with a Mic. It is 20.3 at the chambers. I'll have to shift some pics to a webpage so humor me for a bit.

The French often stamped the finish bore size near the barrel flats. 18.2 and thereabouts is a 12 ga. A 16 is around 17mm, the French tubes (in my limited experience) having a tendency to be slightly over bored, at least in 16's; I have 5 sets of French 16 ga barrels, and they average about .669. And not to steal the thunder from Captain Obvious, the chamber will of course be larger than the bore, to accommodate the shell, and thus the need for a forcing cone.
