It was Ross' articles which led me to purchase a small amount of 7625 to try. He had proclaimed it as the answer to a Damascus lovers dream powder. I did not load an extremely low pressure load but one at about 7K according to the then DuPont load data. After it completely let me down in a duck swamp with temps in the 20°F range I abandoned 7625 forever more.
I still to this say wonder how Ross was able to use those low pressure loads he spoke of in 10 ga for waterfowling. I've never had a lot of warm balmy weather while waterfowl hunting.
Although I always did a good bit of squirrel hunting, though with a .22 LR, I did take some of these loads in the early season just to try them out & they were pure murder on the Bushytails, but just did not endure the cold.
I will say the vast majority of things I ever read in Ross' articles all appeared to be good info, but I do have to take exception to using any "Slow Burn" smokeless powder at very low pressures. I was loading in Rem plastic hulls with recommended power piston wad & recommended mild primer.
I did notice that when the next edition of DuPont's handloaders guide came out this load along with several other lower pressure loads using 7625 had been dropped. Probably I wasn't the only one who encountered problems.
