How have you folks evaluated 4955 (or maybe it was 4451) and compared it to other powders? I was looking at one or the other, trying to see how it compared to those like H-4350, H4831 but all I could find is manufacturing advertising information which was not really what I was after. If I remember correctly, I believe all I came away with was it is manufactured in the way the CFE powders are, to block copper accumulation.

Do you compare them with respect to minimum and maxiumun charge weights, and associated velocities and pressures, or what other things do you look for?
