Bought some N 69 surplus powder. Its labeled made in Scotland so could be a Nobel product. Its rated faster than 2400 and the load data sent with it shows 357 mag velocities with a powder charge about 2 gr less than 2400. Its very coarse and light grey. It's large flat discs. I like 2400 for a lot of Mil-surp rifles. Anyone ever run across this stuff? Mel
