Always double check to see the screw in choke tubes are tight in the bores. Typically, doubles don't have heavy wall tubes in that area, and you want to avoid shooting one out if you can. Use light loads, in either gun, they aren't American guns and you shouldn't feed them American loads. Rather than a textbook, 40 yard approach to patterning the guns, shoot them at ranges that seem typical to the average shots presented to you in your area. The shooters I know that can consistantly grass a pheasant with a full head of steam at forty yards are few, so don't pattern like that is the only shot you will ever take.
I wish you good luck with either gun you decide to keep, and better luck still with the lady who stole your heart.
Best,
Ted
