I opened a can of IMR4895 that I haven't opened in a year and a half. I pour the powder into a clear glass and start weighing some load. I suddenly realize my power is a mixture of the typical black rods that IMR4895 is, and shorter green rod powder. What the heck? Am I forgetting something or has some benchmark or varget gotten mixed into this powder by accident? I think I'm going to flush this can down the drain.
