I no longer have my data for the .38 Super from my 1911. Gone!
I just checked the Hodgon's Annual Manual and none of the data in there was familiar. Seems to me I used Unique and Herco for powders.
Checking an old manual I'd have used, the Lyman Cast Bullet Handbook of the 70's I see 150gr. cast using 5.7gr. Unique for 1,110fps as well as 6.0gr. with 133gr. bullet for 1,200fps.
