2-Piper, SOunds like you were lacking powder in that 7625 Duck Hunt load.
At the same velocities Duponts Charts indicate that 7625 has the same pressures that 2 F black does. CHeck out the Black vs Smokeless articles by Sherman Bell in the SUmmer 2002 page 25. As his tests below indicate for a 3 dr 1 1/8 oz load , 7625 and Black
have the same pressure curve.
