Substitute for old dupont shotshell powder

[Brad4457]

I have an old 1976 Mec shotshell reloader and I used to use DuPont 7625 Powder with the #38 powder bushing for 2-3/4" shells with a 1-1/4 ounce loads for field loads .......is there a substitute powder that I can use with the same old #38 bushing or where do I find this information?
