From my HS-6 Testing in 38 Special, I got the following:
38 Special - Hornady 125 XTP - CCI 500 1.450"
___________________________________________________
Powder Chrg. Avg. Hi Low E.S. S.D. Est. CUP
HS-6 7.0 943 956 929 27 14 15,327
HS-6 7.5 1030 1038 1022 16 8 17,841
HS-6 8.0 1119 1123 1115 8 4 20,675
38 Special - Speer 135 GDHP - CCI 500 1.460"

HS-6 6.5 885 909 851 58 31 14,866
HS-6 7.0 959 963 956 7 6 18,300
HS-6 7.5 1024 1057 1005 52 29 22,412
38 Special - Magma 158 SWC - CCI 500 1.460"

HS-6 6.0 848 853 840 13 7 14,934
HS-6 6.5 938 957 922 35 24 17,115
HS-6 7.0 988 1005 960 45 24 19,498
Note these are measured from a 4" 686 so I think the numbers are real representations of what HS-6 does. Also, the pressures listed are only guesses based on calculations from Hodgdon's published data. They are NOT measured pressure results.
Hope this helps,
