Strange if MRP and Re22 are the exact same powder, that MRP is more consistent from lot to lot. ??? Do Norma apply more quality control when making their own branded powder and slack off a bit when making Re22?
Why wouldn't the two powders exhibit the exact same tolerances if exactly the same powder?
I suspect they arise from the same production line, but are separated by testing. This is not uncommon in various industries. For example, in electronics, different resistors are not made to be 10%, 5%, and 1% accurate. They just make one kind of resistor, then separate them into the different groups by testing for accuracy. (And charge more for 1% than for 10%.)
