Norma 203 powder

[gerber]

I have a full can of Norma 203 powder that is at least 35 years old. Has been sealed and kept dry. Would like to use it but can only find loading data for Norma203B powder.

Norma 203 powder the same as 203B?

I'm in the same boat !

I know this is an old thread, Forgive me !

Guessing those that used Norma 203 powder, are gone by now.
I found an old Hornady Handbook Vol.2. It has the 203 listed for 17 Rem., 224 Weatherby Varmint master, and the 22-250.
I purchased my powder from an estate of an old Benchrest shooter.
It was stored well, as no rust in the can.

So look up some old reloading manuals, and you should be in business.
