Does anyone have a good cross reference of powers by manufacturers.

example:
H-414 is like w760.

thanks

I believe its been discussed once or twice before. Did you use the search function?

Or you could start a new reference here and now.

FYI...I've been told, not only is H414 LIKE W760, it actually is the same powder that comes out of the Primex plant in St. Marks, FLA. Two designations for the very same product, sold by two different companies.

Win 571 same as Hodgdon HS7
Win 540 same as Hodgdon HS6
