Thanks for sharing the results of the testing with us. Both Green Dot and Unique are good powders for use in the short ten. Interestingly enough I have used 27 grains of GD with an SP10 with quarter inch of filler wad for 1 1/4 ounce lead loads in the Federal hull. I will update the short ten reloading data sheet with this info.
