Welcome to the Marlin Forum. Glad to have you with us.
Here is a link to the Hodgdon On-Line Load Datta, http://www.hodgdon.com/index.html
Hope this helps.
Look up Equivalent, then Hodgdon Powders.
There is a very comprehensive guide on the site.
Hodgdon Powder is made by ADI Australia, and there is heaps of load data there.
Be warned, you must know exactly what type of 45-70 rifle you have ie..there are 3 types listed, and a separate one for Ruger #1
