Stan;
I don't recall all the details now but the load was taken directly from a Dupont handloaders guide that was current at the time. I do recall it used Remington SP cases, CCI primers & Rem wads. The load was actually a 1oz load of #5 shot @ about 7K psi. Velocity was around 1150 fps. After loading some prior to the duck season I left the .22 at home a time or so & tried them on some squirrel. They went off with a solid bang & would knock a squirrel for a loop from the top of the tallest trees in my neck of the woods. Then I carried them on that duck hunt. My son & I had gone to this swamp & were hunting from a Jon Boat. There was a flooded Soybean field we had to break ice to get across to the wooded swamp area. First duck I shot at was a Greenhead Mallard drake. I got that feeble Burp I mentioned, the duck came down but hit the water swimming. My son finished him off with a 20 gauge loaded with an ounce of #6's. I didn't shoot anymore but let my Son shoot his limit. When we got home we examined my mallard closely. All the #5 shot had barely broken the skin while his #6 shot had penetrated well. I did note the next edition of DuPont's guide this load had been eliminated, perhaps I wasn't the only one who had trouble with it.
I would advise anyone using 7625 at any load under 8K to pick a load which uses "Hot" components. Maybe if I had been using Federal primers or AA hulls my results would have been different. The SP was a cooler case as well as the CCI primers were mild. Even though listed in their guide it just didn't work well when the weather turned cold. I have done most of my loading with Green Dot since & have had no problems with it plus it was more economical to boot.
