Is it the equivalent to H4831 ? On the box it states do not use IMR 4831 data. Would like to use this in my .338 win mag /250gr load and .270 win. 130gr .Was it made by Nobel ?
 
If the powder is labelled H48, that is the Nobel equivalent to H4831. Great stuff in the .270.

I split a bulk box of it with a buddy in the early 80's couldn't recall what data we used . Found a old target 74gr in Win .338win mag Win brass and a Hornady 225grSP 3 shots touching.
