I appreciate the input, The Vitavhouri powders are quite expensive and I was hoping to get this done with what I have on hand. since AA7 was recommended, I remembered at one time I had some AA9, so I went and looked and on the back of the shelf I found a small amount of AA9, since I am only wanting to load about 50 rounds for SD, I have enough left. would this be a better choice ? as it has been stated that spherical powders have less flash. if not then I guess I'll have to wait till I can pick up some more powder.
superspirit, AA#9 is an excellent .357 Magnum powder. I would definitely use it over the other powders you mentioned. I can't speak for its flash in short barrels but it gives very good accuracy and velocity. It might actually work pretty well in that Accurates Start Charges with #9 may be all the performance you're looking for. Keep in mind that their data was worked up with a 6" barrel and you're gonna lose some velocity. But with the lower powder charge, flash will also be less than the top-end loads. Since you are loading for defense and flash is important, you might want to test some handloads by shooting some at night if possible.
