Thank you Bill, it was kind of a fun task and didn't seem like work. PDF is great but Excel is very powerful tool and lets me sort the data how I desire, say by powder type or pressure or any combination. You are right when you say we don't need any 1285 to 1360 fps loads, 1150 to 1200 is where I want my loads to be. As you can see pressures were not given by Hercules in the 60's and early 70's. In spite of the lack of Rem SP hulls, 57 primers and the convenience of the SP10 wad vs card wad columns I think this gives a good idea of the powders that will work and idea of how much of them to use. If I find additional data I'll update this sheet and repost. I wrote to Alliant about loads for the short ten and my use with some of their powders, as yet no response. In the meantime I plan to use my head and play with Green Dot and Unique loadings. If they shoot consistently with good results over time I will probably send them off to Precision Reloading and get the velocity and pressure data from a 5 shot string.
