I was going through my powder stash and was going to add a small amount of 4227 I had left into a newer bottle of it I had opened. There was not much left in the older bottle, so I figured a good shake up and all would be well.
Before I poured it in I decided to take a look because something struck me as odd. Turns out the two powders looked totally different. I’ve never run into this before. I’ve had both bottles since new. Shot rounds out of both.
Is this something that happens, same powder but different lots have such different length grains? Just seems too much of a difference to be right. I cannot say I remember shooting the same load from each canister. I always work up a load when getting a new can.
I think I had worked up a load, then loaded a bunch, and then decided to get another can for another project, and not wanting to start over I just started loading from the new can.
