You won't be fond to the price but Vihtavouri 3N37 sits dead even with SR4756 on Western Powders Burn Rate chart. I use 3N37 for 38 special and heavy bullet 9mm loads and can state that it meters wonderfully and shoots cleanly. Accuracy and consistency from shot to shot is also excellent.
I am also a user of SR7625 and stocked up when it was announced it was being discontinued. Once that's gone I'm not sure of what I use for a replacement but Accurate #5 and VV N-330 are two alternates I'm considering. Experience using Accurate #5 for reduced energy 357 Magnums and hotter 45 ACP loads indicates it will work, however I don't know if anything will reproduce the soft recoil impulse of the SR7625.
