I have used plenty of MRP over the years and have found it to be more consistent than Reloder 22.
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.
