The 1335 load with 1oz shot was the 3 3/4 dram equivalent (AKA Express, SuperX, HiPower etc). The 3 DE load with 1oz shot was around 1225. It used to be referred to as the "Super Trap" load & was most often found in #7 size shot.
After a bad experience with 7625 personally I do not Trust, any slow burning powder loaded to pressures below about 8K for hunting use when temps may drop. Virtu8ally all of these slow burning powders were designed to carry heavier shot loads, higher velocities or a combination of both without exceeding max pressures. they were "NOT" designed to burn at low pressures. The very properties which make them suitable for the high end of the spectrum is what makes the "Unsuitable" for the low end, especially when the temps drop down around freezing.
