Well, JB, we've had this discussion before but I won't go there today.

But let's just review a few things said in this thread:

Norma guys says they are the same
Powder kernels color are not the same; some say yes, some say not. I say no & I have lots form both over various time periods
Norma & your experience say MRP is more consistent


So are they they same???????????

I say no from the appearance standpoint alone.MPR clearly meters better/easier for me through a Redding powder feeder.

I say yes from the performance standpoint & (my) load data.

Can't comment on the variability as I haven't checked it close enough to say.

But if there is real data from Norma, or anyone else claiming/showing measurably less variance with MRP, then to me, that is pretty conclusive that they are not (exactly) the same powders & that there is something different in them.

Does it matter? I don't think so, & I have enough of both for a long time.

Same formulation, same coatings, same environmental protocols for production, different QC standards. So what Norma would reject as outside of their specs, Alliant would accept, as their specs are broader.
