Hello Tom,

As you point out when not for slugs, French guns, such as this one, will be marked
"Non Pour la Balle". This one is marked "Raye" or rifled.

Also to bear in mind, normally guns with dispersion rifling are used for becasse and
are very light guns such as the Baby Bretons, for a lot of walking and very little
shooting. Not in this case. JMTC.
