I will only comment that I have found over the years that Unique, as accurate as it can be, is a pain in the posterior to through small volume charges "consistently". I have had this bulky powder bridge the drop tube and short rounds and then dump the excess in the next case. For this reason I will not use it on my Dillon, only small batches where I can look into all the filled cases and inspect the powder level before seating any bullets. Also, because of the bulkiness of the powder, it is dirty and leaves some large granules in the action. The residue is bad enough in a revolver, but can be a problem in a semi-auto. Lyman makes a good loading manual and has lots of data for pistol calibers.
