I have been loading primarily Green Dot. There are also some good light loads using Red Dot. Many have reported good results with PB which has a similar burn rate to GD & there are similar powders by other makers. I am firmly of the belief that powders slower than this should be used at pressures below about 8K psi, "Only" in hot cases (AA, STS etc), with a hot primer, & then only in warm to hot temperatures. I am fully aware there are those who disagree, but they may change their minds one day. A 7625 load taken directly from the manual giving 1¼oz shot about 1125-1150 fps @ around 7K psi, put up in Rem SP cases with Power Piston wads & CCI primers, totally let me down in a duck swamp with temps in the 20sF one day. This was back in the late 70's & was still DuPont powder. Then later upon learning of the distinct possibility of a secondary combustion producing an effect very similar to an obstruction & with the possible result being a burst bbl, I totally swore off of slow burning smokeless powder loads giving low pressures.
