When I did extensive testing to duplicate the FBI Load I found several powders that easily out did Unique. One of those powders was HS-6 and that's what I settled on.

Warning, even though I highly doubt this load is over the 20,000 psi SAAMI limit the charge Wright is over current published data. (current, not older data)

Here's the load:
Winchester .38 Special +P case
158gr Hornady LSWC/HP
CCI 550 Primer (Magnum primer on this load)
7.0gr HS-6
COL 1.475"
4" M686 ---- 2" M640
927.0 -- AV --- 888.9
955.1 --- H --- 897.1
905.4 --- L --- 876.6
49.7 ---- ES --- 20.5
20.7 ---- SD ---- 7.9
17.0 ---- AD ---- 5.9

Use this data at your own risk. If you blow anything up blame no one but yourself. I have shot hundreds of this load in a bunch of revolvers including a M10 and M442.
