Well, there's this link -
John R. Clarke Article
Somewhere in the middle of the article, the author says, "There are other powders, for example Hodgdon's BL-C(2) and H-335, that will give performance about like that of Win. 748 Ball."
The table above (for 150gr bullets) shows loads of 49-50gr of Win 748.
My experience is with Varget, so I can't personally endorse H-335...but the above (often referenced) article seems to indicate that it has been used in the Garand.
