The sc version is supposed to be of the same burn rate as the older long kernal powder. BUT the last jug I got of sc was extremely slow burning. (like a good 100-150 fps slower than it should have been). Maybe I just got a slow powder lot. Many manuals say powder rates can be off by 5% and I guess that just puts my jug at the far end of of that perameter. It sure meters nice--it's really hard to load IMR powder after loading Hodgdon and Reloader's short kernals.
I buy all my powder in 5-8 lb containers, reason for this is because I don't think powders are as consistent as the makers would have you think!With large ammounts of powder that is the same you will have a lot of shooting consistency within the batch.I also shoot a lot of military surplus propellant, there are many burn rates to meet many loading requirments at a very inexpensive price!!!My $1.
Good point. What I didn't add is I also buy H4831SC in 8 lb containers for the same reason, but the different lots I have bought thus far (I have bought 1 lb containers on rare occasion) have been very consistant.
