Norma 202 and Reloder 12

[fuzzy39]

Does anyone know if Norma 202 and Reloder 12 are in fact the same thing?
I have 45 rounds or 358 handloads using Norma 202 powder and 250 gr Speer Bullets. I bought these as a package of 358 stuff from a trusted Handloader but I do like to confirm data. I have found old data with reloder 12 in the mighty 358 and have read they are the same.

I’d like to confirm this load is safe, pull a few bullets to confirm the powder weight and shoot the rest.

Thanks in advance.

I use Reloder 12 in my 222 Remington, and still have a bit of this obsolete number stashed away.
It is not too much different in burn rate than N202, but they are not identical. I would start low
and work up carefully. Dave.
