Johnn, I have one cartridge only, of #3 shot. That would do when they got beyond range of your #7! Only problem is mine is a 16 gauge.
The low brass base is marked, "DOMINION REGAL, No 16.
The wad on the front is marked with a good sized, "3."
On the rim of the wad, partially covered by the fold of the case, is marked, "BALLISTITE."
On the opposite side of the wad is the famous, D.C. Co.
Maybe Ganderite would know something about it.
