Ted and Rem,
The Regis Darne 10 gauge, F Darne fils aime 16 gauge, and Charlin 12 gauge are in The DGJ Vol 26 Issue 1 of 2015.

The 10 gauge weighs 7 lbs 2 oz. after I had Darne put a new stock on it. Darne also submitted the gun to proof at St. Etienne and it has superior proof marks. New barrels were needed after Briley messed up cutting for choke tubes and handsomely paid Kirk Merrington to make new barrels.

I've used the gun for geese, handloading #2 NICE shot in cut down (to 2-7/8 in)Federal primed hulls. Have also used it for upland birds and, of course, recently for turkey!

Regards, Tim
